Ensure logging is configured for CLI commands
Any CLI commands that depend on core Elasticsearch might touch classes
(directly or indirectly) that depends on logging. If they do this and
logging is not configured, Log4j will dump status error messages to the
console. As such, we need to ensure that any such CLI command configures
logging (with a trivial configuration that dumps log messages to the
console). Previously we did this in the base CLI command but with the
refactoring of this class out of core Elasticsearch, we no longer
configure logging there (since we did not want this class to depend on
settings and logging). However, this meant for some CLI commands (like
the plugin CLI) we were no longer configuring logging. This commit adds
base classes between the low-level command and multi-command classes
that ensure that logging is configured. Any CLI command that depends on
core Elasticsearch should use this infrastructure to ensure logging is
configured. There is one exception to this: Elasticsearch itself because
it takes reponsibility into its own hands for configuring logging from
Elasticsearch settings and log4j2.properties. We preserve this special
status.

Automatically prepare indices for splitting (#27451)
Today we require users to prepare their indices for split operations.
Yet, we can do this automatically when an index is created which would
make the split feature a much more appealing option since it doesn't have
any 3rd party prerequisites anymore.

This change automatically sets the number of routinng shards such that
an index is guaranteed to be able to split once into twice as many shards.
The number of routing shards is scaled towards the default shard limit per index
such that indices with a smaller amount of shards can be split more often than
larger ones. For instance an index with 1 or 2 shards can be split 10x
(until it approaches 1024 shards) while an index created with 128 shards can only
be split 3x by a factor of 2. Please note this is just a default value and users
can still prepare their indices with `index.number_of_routing_shards` for custom
splitting.

NOTE: this change has an impact on the document distribution since we are changing
the hash space. Documents are still uniformly distributed across all shards but since
we are artificually changing the number of buckets in the consistent hashign space
document might be hashed into different shards compared to previous versions.

This is a 7.0 only change.

Cross Cluster Search: make remote clusters optional (#27182)
Today Cross Cluster Search requires at least one node in each remote cluster to be up once the cross cluster search is run. Otherwise the whole search request fails despite some of the data (either local and/or remote) is available. This happens when performing the _search/shards calls to find out which remote shards the query has to be executed on. This scenario is different from shard failures that may happen later on when the query is actually executed, in case e.g. remote shards are missing, which is not going to fail the whole request but rather yield partial results, and the _shards section in the response will indicate that.

This commit introduces a boolean setting per cluster called search.remote.$cluster_alias.skip_if_disconnected, set to false by default, which allows to skip certain clusters if they are down when trying to reach them through a cross cluster search requests. By default all clusters are mandatory.

Scroll requests support such setting too when they are first initiated (first search request with scroll parameter), but subsequent scroll rounds (_search/scroll endpoint) will fail if some of the remote clusters went down meanwhile.

The search API response contains now a new _clusters section, similar to the _shards section, that gets returned whenever one or more clusters were disconnected and got skipped:

"_clusters" : {
    "total" : 3,
    "successful" : 2,
    "skipped" : 1
}
Such section won't be part of the response if no clusters have been skipped.

The per cluster skip_unavailable setting value has also been added to the output of the remote/info API.

Use CoveringQuery to select percolate candidate matches and
extract all clauses from a conjunction query.

When clauses from a conjunction are extracted the number of clauses is
also stored in an internal doc values field (minimum_should_match field).
This field is used by the CoveringQuery and allows the percolator to
reduce the number of false positives when selecting candidate matches and
in certain cases be absolutely sure that a conjunction candidate match
will match and then skip MemoryIndex validation. This can greatly improve
performance.

Before this change only a single clause was extracted from a conjunction
query. The percolator tried to extract the clauses that was rarest in order
(based on term length) to attempt less candidate queries to be selected
in the first place. However this still method there is still a very high
chance that candidate query matches are false positives.

This change also removes the influencing query extraction added via #26081
as this is no longer needed because now all conjunction clauses are extracted.

Die with dignity while merging
If an out of memory error is thrown while merging, today we quietly
rewrap it into a merge exception and the out of memory error is
lost. Instead, we need to rethrow out of memory errors, and in fact any
fatal error here, and let those go uncaught so that the node is torn
down. This commit causes this to be the case.

Correctly encode warning headers
The warnings headers have a fairly limited set of valid characters
(cf. quoted-text in RFC 7230). While we have assertions that we adhere
to this set of valid characters ensuring that our warning messages do
not violate the specificaion, we were neglecting the possibility that
arbitrary user input would trickle into these warning headers. Thus,
missing here was tests for these situations and encoding of characters
that appear outside the set of valid characters. This commit addresses
this by encoding any characters in a deprecation message that are not
from the set of valid characters.

Luca Cavanna 9b9cb81c41 Fix serialization errors when cross cluster search goes to a single shard (#26881)
The single shard optimization that we have in our search api changes the type of response returned by the query transport action name based on the shard search request. if the request goes to one shard, we will do query and fetch at the same time, hence the response will be different. The proxying layer used in cross cluster search was not aware of this distinction, which causes serialization issues every time a cross cluster search request goes to a single shard and goes through a gateway node which has to forward the shard request to a data node. The coordinating node would then expect a QueryFetchSearchResult while the gateway would return a QuerySearchResult.

Boaz Leskes cd2a4372b4 RecoveryIT should wait for green when in mixed cluster to avoid unassigned shards
The test starts with two old nodes and creates indices (without waiting for green, which is fixed here too). Then it restarts one of the nodes and waits for it to join the cluster. This wait condition only uses wait for yellow as our generic infra doesn't how many nodes are there in total. Once the restarted node is part of the cluster (mixed mode) the second old node is restarted. If indices are not fully allocated when that happens, the shards will go into delayed unassigned mode. If the recovery of the replica never completed we may end up with corrupted / no secondary copy on the node. This will cause the shards to be delayed for 1m before being reassigned and the test will time out.

Jason Tedor f35d1de502 Introduce global checkpoint background sync
It is the exciting return of the global checkpoint background
sync. Long, long ago, in snapshot version far, far away we had and only
had a global checkpoint background sync. This sync would fire
periodically and send the global checkpoint from the primary shard to
the replicas so that they could update their local knowledge of the
global checkpoint. Later in time, as we sped ahead towards finalizing
the initial version of sequence IDs, we realized that we need the global
checkpoint updates to be inline. This means that on a replication
operation, the primary shard would piggy back the global checkpoint with
the replication operation to the replicas. The replicas would update
their local knowledge of the global checkpoint and reply with their
local checkpoint. However, this could allow the global checkpoint on the
primary to advance again and the replicas would fall behind in their
local knowledge of the global checkpoint. If another replication
operation never fired, then the replicas would be permanently behind. To
account for this, we added one more sync that would fire when the
primary shard fell idle. However, this has problems:
 - the shard idle timer defaults to five minutes, a long time to wait
   for the replicas to learn of the new global checkpoint
 - if a replica missed the sync, there was no follow-up sync to catch
   them up
 - there is an inherent race condition where the primary shard could
   fall idle mid-operation (after having sent the replication request to
   the replicas); in this case, there would never be a background sync
   after the operation completes
 - tying the global checkpoint sync to the idle timer was never natural

To fix this, we add two additional changes for the global checkpoint to
be synced to the replicas. The first is that we add a post-operation
sync that only fires if there are no operations in flight and there is a
lagging replica. This gives us a chance to sync the global checkpoint to
the replicas immediately after an operation so that they are always kept
up to date. The second is that we add back a global checkpoint
background sync that fires on a timer. This timer fires every thirty
seconds, and is not configurable (for simplicity). This background sync
is smarter than what we had previously in the sense that it only sends a
sync if the global checkpoint on at least one replica is lagging that of
the primary. When the timer fires, we can compare the global checkpoint
on the primary to its knowledge of the global checkpoint on the replicas
and only send a sync if there is a shard behind.

Boaz Leskes 04385a9ce9 Restoring from snapshot should force generation of a new history uuid (#26694)
Restoring a shard from snapshot throws the primary back in time violating assumptions and bringing the validity of global checkpoints in question. To avoid problems, we should make sure that a shard that was restored will never be the source of an ops based recovery to a shard that existed before the restore. To this end we have introduced the notion of `histroy_uuid` in #26577 and required that both source and target will have the same history to allow ops based recoveries. This PR make sure that a shard gets a new uuid after restore.

As suggested by @ywelsch , I derived the creation of a `history_uuid` from the `RecoverySource` of the shard. Store recovery will only generate a uuid if it doesn't already exist (we can make this stricter when we don't need to deal with 5.x indices). Peer recovery follows the same logic (note that this is different than the approach in #26557, I went this way as it means that shards always have a history uuid after being recovered on a 6.x node and will also mean that a rolling restart is enough for old indices to step over to the new seq no model). Local shards and snapshot force the generation of a new translog uuid.

Boaz Leskes 1ca0b5e9e4 Introduce a History UUID as a requirement for ops based recovery (#26577)
The new ops based recovery, introduce as part of  #10708, is based on the assumption that all operations below the global checkpoint known to the replica do not need to be synced with the primary. This is based on the guarantee that all ops below it are available on primary and they are equal. Under normal operations this guarantee holds. Sadly, it can be violated when a primary is restored from an old snapshot. At the point the restore primary can miss operations below the replica's global checkpoint, or even worse may have total different operations at the same spot. This PR introduces the notion of a history uuid to be able to capture the difference with the restored primary (in a follow up PR).

The History UUID is generated by a primary when it is first created and is synced to the replicas which are recovered via a file based recovery. The PR adds a requirement to ops based recovery to make sure that the history uuid of the source and the target are equal. Under normal operations, all shard copies will stay with that history uuid for the rest of the index lifetime and thus this is a noop. However, it gives us a place to guarantee we fall back to file base syncing in special events like a restore from snapshot (to be done as a follow up) and when someone calls the truncate translog command which can go wrong when combined with primary recovery (this is done in this PR).

We considered in the past to use the translog uuid for this function (i.e., sync it across copies) and thus avoid adding an extra identifier. This idea was rejected as it removes the ability to verify that a specific translog really belongs to a specific lucene index. We also feel that having a history uuid will serve us well in the future.

Jason Tedor 7a035f5f84 setgid on /etc/elasticearch on package install
When creating the keystore explicitly (from executing
elasticsearch-keystore create) or implicitly (for plugins that require
the keystore to be created on install) on an Elasticsearch package
installation, we are running as the root user. This leaves
/etc/elasticsearch/elasticsearch.keystore having the wrong ownership
(root:root) so that the elasticsearch user can not read the keystore on
startup. This commit adds setgid to /etc/elasticsearch on package
installation so that when executing this directory (as we would when
creating the keystore), we will end up with the correct ownership
(root:elasticsearch). Additionally, we set the permissions on the
keystore to be 660 so that the elasticsearch user via its group can read
this file on startup.

Michael Basnight cfd14cd2b8 Revert shading for the low level rest client (#26367)
At current, we do not feel there is enough of a reason to shade the low
level rest client. It caused problems with commons logging and IDE's
during the brief time it was used. We did not know exactly how many
users will need this, and decided that leaving shading out until we
gather more information is best. Users can still shade the jar
themselves. For information and feeback, see issue #26366.

Ryan Ernst 5202e7e93b Settings: Move keystore creation to plugin installation (#26329)
This commit removes the keystore creation on elasticsearch startup, and
instead adds a plugin property which indicates the plugin needs the
keystore to exist. It does still make sure the keystore.seed exists on
ES startup, but through an "upgrade" method that loading the keystore in
Bootstrap calls.

Luca Cavanna 6d8e2c6d4c Make RestHighLevelClient Closeable and simplify its creation (#26180)
By making RestHighLevelClient Closeable, its close method will close the internal low-level REST client instance by default, which simplifies the way most users interact with the high-level client.

Its constructor accepts now a RestClientBuilder, which clarifies that the low-level REST client is internally created and managed.

It is still possible to provide an already built `RestClient` instance, but that can only be done by subclassing `RestHighLevelClient` and calling the protected constructor that accepts a `RestClient`. In such case a consumer has also to be provided, which controls what has to be done when the high-level client gets done.

Jason Tedor 4e97be02a9 Export HOSTNAME environment variable
We previously explicitly set the HOSTNAME environment variable so that
${HOSTNAME} could be used a placeholder for defining the node.name in
elasticsearch.yml. We removed explicitly setting this because bash
defines HOSTNAME. The problem is that bash defines HOSTNAME as a bash
variable, not as an environment variable. Therefore, to restore the
previous behavior, we export the bash value for HOSTNAME as an
environment variable named HOSTNAME. For consistency between Windows and
the Unix-like systems, we also define HOSTNAME with a value equal to the
environment variable COMPUTERNAME on Windows.

it's too generic. This commit renames CONF_DIR to ES_PATH_CONF.

Simon Willnauer e81804cfa4 Add a shard filter search phase to pre-filter shards based on query rewriting (#25658)
Today if we search across a large amount of shards we hit every shard. Yet, it's quite
common to search across an index pattern for time based indices but filtering will exclude
all results outside a certain time range ie. `now-3d`. While the search can potentially hit
hundreds of shards the majority of the shards might yield 0 results since there is not document
that is within this date range. Kibana for instance does this regularly but used `_field_stats`
to optimize the indexes they need to query. Now with the deprecation of `_field_stats` and it's upcoming removal a single dashboard in kibana can potentially turn into searches hitting hundreds or thousands of shards and that can easily cause search rejections even though the most of the requests are very likely super cheap and only need a query rewriting to early terminate with 0 results.

This change adds a pre-filter phase for searches that can, if the number of shards are higher than a the `pre_filter_shard_size` threshold (defaults to 128 shards), fan out to the shards
and check if the query can potentially match any documents at all. While false positives are possible, a negative response means that no matches are possible. These requests are not subject to rejection and can greatly reduce the number of shards a request needs to hit. The approach here is preferable to the kibana approach with field stats since it correctly handles aliases and uses the correct threadpools to execute these requests. Further it's completely transparent to the user and improves scalability of elasticsearch in general on large clusters.
