Today, we disable CORS by default, but if a user simply enables CORS their instance of
elasticsearch will allow cross origin requests from anywhere, as the default value for allowed
origins is `*`.
This changes the default to be `null` so that no origins are allowed and the user must explicitly
specify the origins they wish to allow requests from. The documentation also mentions that there
is a security risk in using `*` as the value.

some cosmetic fixes (making members final where possible, avoiding this

In addition to that this PR changes:
* prevent NPEs in doXContent when rendering out nested queries that are null. We now render out empty object ({ }) which then gets parser to null to be consistent with queries than come only through the rest layer
* prevent adding nested null queries to collections of clauses like in BoolQueryBuilder
* add validate() method to all builders (even when empty)

Today we are very lenient in parsing the translog files. This is
actually not necessary since we have a clear run once upgrade path.
All files are converted into the new file name pattern such that we
only need to look at old file patterns in the context of the upgrade.
This commit makes parsing really strict with the exceptoin of the upgrade path.
This adds a new pipeline aggregation, the cumulative sum aggregation. This is a parent aggregation which must be specified as a sub-aggregation to a histogram or date_histogram aggregation. It will add a new aggregation to each bucket containing the sum of a specified metrics over this and all previous buckets.
Today we mark a translog as upgraded by adding a marker to the engine commit.
Yet, this commit was only added if there was no translog present before ie. only
if we have a fresh engine which is missing the entire point. Yet, this commit
adds a backwards index tests that ensures we can open old indices more than once
ie. mark the index as upgraded.

In Lucene 5x the exception thrown when highlighter encounters a huge term

Several classes have been collapsed into IndexShard and IndexShardGatewayService

This commit folds ShardRouting, ImmutableShardRouting and MutableShardRouting

This commit makes the get and search APIs always return `_parent`, `_routing`,

Currently the filter cache is configured to have a maximum size in bytes of 10%
of the JVM memory, and a maximum number of cached filters (across all segments
of all shard on the same node) of 100000. I would like to change the latter to
a more reasonable value of 1000.
Given that we track the most 256 most recently used filters per index and only
cache those that have been seen 5 times or more, a single index cannot have more
than 50 hot filters, so a maximum number of cached filters of 1000 per node
should be more than necessary.
Today, we have scheduled reroute that kicks every 10 seconds and checks if a
reroute is needed. We use it when adding nodes, since we don't reroute right
away once its added, and give it a time window to add additional nodes.
We do have recover after nodes setting and such in order to wait for enough
nodes to be added, and also, it really depends at what part of the 10s window
you end up, sometimes, it might not be effective at all. In general, its historic
from the times before we had recover after nodes and such.
This change removes the 10s scheduling, simplifies RoutingService, and adds
explicit reroute when a node is added to the system. It also adds unit tests
to RoutingService.

Since elasticsearch doesn't shade artifacts anymore (see #11522), the dependencies list for RPM/DEB must be updated. Now we package all maven libs by default except the generated -shaded/-tests/-test-cours JARs and slf4j-api (marked as optionnal).
We currently are very lax about allowing data types to conflict for the
same field name, across document types. This change makes the underlying
map in MapperService a 1-1 map of field name to field type, and throws
exception when new types are not compatible.
To still allow changing a type, with parameters that are allowed to be
changed, but for a field that exists in multiple types, a new parameter
to index creation and put mapping API is added: update_all_types.
This defaults to false, and the exception messages suggest using
this parameter when trying to modify a setting that is allowed to be
modified but is being limited by this restriction.
There are also a couple changes which try to base fields from new types
for dynamic mappings, and root mappers, on existing settings. For
dynamic mappings this is important if the dynamic defaults have been
changed. For root mappings, this is mostly just for backcompat when
pre 2.0 root mappers could have their field type changed.

The commit about adding cluster health response features also removed

If we mark the shard as being in POST_RECOVERY before the percolator
is fully set up we might expose it to the user as fully searchable before
all queries are loaded. This can lead to wrong results especially in tests
when a shard is concurrently marked as STARTED.
This commit also removes unneded abstractions on IndexShard where readoperations
should be allowed when the purose is a write.
It is handy to have a base interface, not just an abstract class, for all of our query builders. This gives us more flexibility especialy with complex class hierarchies. For instance SpanTermQueryBuilder extends BaseTermQueryBuilder, but also needs to be marked as a SpanQueryBuilder. The latter is a marker interface that should extend QueryBuilder which is not possible unless QueryBuilder actually is an interface.
Also remove queryId method as it created confusion, getName is good enough for the purpose, and override the return type of toQuery method for SpanQueryBuilders to SpanQuery.

In order to get a quick overview using by simply checking the cluster state

to the cluster health response:
* task max waiting time, the time value of the first task of the

* active shards percent: The percentage of the number of shards that are in
initializing state
This makes the cluster health API handy to check, when a fully restarted
cluster is back up and running.

The change makes rest-spec-api a project in the same way as we build dev-tools. it packages the tests and api in a bundle using the maven-remote-resources-plugin and uses the same plugin in the plugins and core pom to unpack the rest-api-spec into the target directory and references the rest tests there in the test resources.
The main stimulus for this change is that for those using Eclipse the current build does not work. After running `mvn eclipse:eclipse` the Eclipse IDE errors because the rest-api-spec is outside of the project scope, meaning that every time the command is run (required whenever any dependencies change), the class path of all the projects has to be manually fixed.

Tests relying on sleeps and latch timeouts are prone to weird timing issues

For #8871, we need to be able to check field types are compatible,
without comparing FieldMappers. This change moves the simulation
checks (which generate merge conflicts) for any properties of
MappedFieldTypes into a new method, validateCompatible.
This also simplifies the merge code which merges settings
between the old and new fieldtypes. Previously, each subclass
of FieldMapper would have to set its own fieldtype settings.
However, now that we have .clone(), which perfectly copies
all properties (with subclasses accounted for), we can now
do a simple clone when merging.
Finally, this fixes a subtle bug in merging, in which if
merging has conflicts, and we were not simulating, we would
still update the field type, even though it was not compatible!
NOTE: there is one test failure I am trying to track down with
timestamp merging. Otherwise, all tests pass.
Currently, we delete the shard _state file on engine failure.
This behaviour does not persist the engine failure reason for later inspection.
This commit marks the shard store as corrupted instead of deleting
the _state file to ensure the store index can not be opened after and
the engine failure is persisted.
CommonTermsQueryParser does not check for disable_coords, only for
disable_coord. Yet the builder only outputs disable_coords, leading to
disabling the coordination factor to be ignored in the Java API.

When using compression over the network, you might sometimes see warnings that
the stream was not fully read. This is because DeflaterOutputStream adds an
end-of-stream marker. When deserializing, we need to poll for one byte using
InputStream.read() to make sure to decode this EOS marker.
For the record, it does not strike all the time today because we perform
buffering when decompressing to avoid performing too many JNI calls, but it
is easy to make this warning happen all the time by decreasing the size of
the buffer we use.

Allow to set delayed allocation timeout on unassigned shards when a node leaves the cluster. This allows to wait for the node to come back for a specific period in order to try and assign the shards back to it to reduce shards movements and unnecessary relocations.
The setting is an index level setting under `index.unassigned.node_left.delayed_timeout` and defaults to 0 (== no delayed allocation). We might want to change the default, but lets do it in a different change to come up with the best value for it. The setting can be updated dynamically.
When shards are delayed, a log message with "info" level will notify how many shards are being delayed.
An implementation note, we really only need to care about delaying allocation on unassigned replica shards. If the primary shard is unassigned, anyhow we are going to wait for a copy of it, so really the only case to delay allocation is for replicas.

The cache we are using for fielddata reclaims memory lazily/asynchronously. While this

are invalidated because segments or readers are closed, which is important since such

Now that doc values are the default for fielddata, specialized in-memory

The AsyncShardFetch retrieves shard information from the different nodes in order to detirment the best location for unassigned shards. The class uses TransportNodesListGatewayStartedShards and TransportNodesListShardStoreMetaData in order to fetch this information. These actions, inherit from TransportNodesAction and are activated using a list of node ids. Those node ids are extracted from the cluster state that is used to assign shards.
If we perform a reroute and adding new news in the same cluster state update task, it is possible that the AsyncShardFetch administration is based on
a different cluster state then the one used by TransportNodesAction to resolve nodes. This can cause a problem since TransportNodesAction filters away unkown nodes, causing the administration in AsyncShardFetch to get confused.
This commit fixes this allowing to override node resolving in TransportNodesAction and uses the exact node ids transfered by AsyncShardFetch
Information about in-progress snapshot and restore processes is not really metadata and should be represented as a part of the cluster state similar to discovery nodes, routing table, and cluster blocks.

As part of the query refactoring, we want to be able to serialize queries by having them extend Writeable, rather than serializing their json. When reading them though, we need to be able to identify which query we have to create, based on its name.
For this purpose we introduce a new abstraction called NamedWriteable, which is supported by StreamOutput and StreamInput through writeNamedWriteable and readNamedWriteable methods. A new NamedWriteableRegistry is introduced also where named writeable prototypes need to be registered so that we are able to retrieve the proper instance of query given its name and then de-serialize it calling readFrom against it.

While we had initially planned to keep rivers around in 2.0 to ease migration,
keeping support for rivers is challenging as it conflicts with other important
changes that we want to bring to 2.0 like synchronous dynamic mappings updates.
Nothing impossible to fix, but it would increase the complexity of how we
deal with dynamic mappings updates and manage rivers, while handling dynamic
mappings updates correctly is important for resiliency and rivers are on the go.
So removing rivers in 2.0 may well be a better trade-off.
These methods are now all in MappedFieldType. This removes the remaining
callers of the methods on FieldMapper, and cuts down the FieldMapper
API to no longer include them.
The MapperService is the "index wide view" of mappings. Methods on it
are used at query time to lookup how to query a field. This
change reduces the exposed api so that any information returned
is limited to that api exposed by MappedFieldType. In the future,
MappedFieldType will be guaranteed to be the same across all
document types for a given field.
Note CompletionFieldType needed some more settings moved to it. Other
than that, this change is almost purely cosmetic.

After asynchronously fetching shard information the gateway allocator issues a reroute via a cluster state update task. #11421 introduced an optimization trying to avoid submitting unneeded reroutes when results for many shards come in together. This is done by having a rerouting flag, indicating a pending reroute is coming and thus any new incoming shard info doesn't need to issue a reroute. This flag wasn't reset upon an error in the reroute update task. Most notably - if a master node had to step during to a min_master_node violation, it could reject an ongoing reroute. Lacking to reset the flag causing it to skip any future reroute, when the node became master again.

Since we are creating write.lock earlier now, blob store shouldn't attempt deleting this file during clean up at the end of the restore process. The file is locked and the blog store doesn't succeed, but it generates a lot of useless warnings "failed to delete file [write.lock] during snapshot cleanup".
Closes#11517
