Adding methods and tests to ScriptSortBuilder that makes it implement NamedWritable and adds a fromXContent() method needed to read itseld from xContent. Also changing sortMode() setters in
FieldSortBuilder, GeoDistanceSortBuilder and ScriptSortBuilder to accept an enum instead of a String
value.

IndicesStore checks for `allocated elsewhere` for every shard not alocated on the local node
On each cluster-state update we check on the local node if we can delete some shards content.
For this we linearly walk all shards and check if they are allocated and started on another node
and if we can delete them locally. if we can delete them locally we go and ask other nodes if we can
delete them and then if the shared IS active elsewhere issue a state update task to delete it. Yet,
there is a bug in IndicesService#canDeleteShardContent which returns `true` even if that shards
datapath doesn't exist on the node which causes tons of unnecessary node to node communication and
as many state update task to be issued. This can have large impact on the cluster state processing
speed.
**NOTE:** This only happens for shards that have at least one shard allocated on the node ie. if an `IndexService` exists.

Add infrastructure to run REST tests on a multi-version cluster
This change adds the infrastructure to run the rest tests on a multi-node
cluster that users 2 different minor versions of elasticsearch. It doesn't implement
any dedicated BWC tests but rather leverages the existing REST tests.
Since we don't have a real version to test against, the tests uses the current version
until the first minor / RC is released to ensure the infrastructure works.
Given the amount of problems this change already found I think it's worth having this run with our test suite by default. The structure of this infra will likely change over time but for now it's a step into the right direction. We will likely want to split it up into integTests and integBwcTests etc. so each plugin can have it's own bwc tests but that's left for future refactoring.
After another round of input from @cbuescher this adds a few more sanity
checks to request parsing.
In addition adds (back) support for the reverse option.
Today index names are often resolved lazily, only when they are really
needed. This can be problematic especially when it gets to mapping updates
etc. when a node sends a mapping update to the master but while the request
is in-flight the index changes for whatever reason we would still apply the update
since we use the name of the index to identify the index in the clusterstate.
The problem is that index names can be reused which happens in practice and sometimes
even in a automated way rendering this problem as realistic.
In this change we resolve the index including it's UUID as early as possible in places
where changes to the clusterstate are possible. For instance mapping updates on a node use a
concrete index rather than it's name and the master will fail the mapping update iff
the index can't be found by it's <name, uuid> tuple.
Closes#17048
Changes:
- no more option to configure eager/lazy loading of the norms (useless now
that orms are disk-based)
- only the `string`, `text` and `keyword` fields support the `norms` setting
- the `norms` setting takes a boolean that decides whether norms should be
stored in the index but old options are still supported to give users time
to upgrade
- setting a `boost` no longer implicitely enables norms (for new indices only,
this is still needed for old indices)
To make API's output more easy to read we are suppressing stack traces (#12991) unless explicitly requested by setting `error_trace=true` on the request. To compensate we are logging the stacktrace into the logs so people can look it up even the error_trace wasn't enabled. Currently we do so using the `INFO` level which can be verbose if an api is called repeatedly by some automation. For example, if someone tries to read from an index that doesn't exist we will respond with a 404 exception and log under info every time. We should reduce the level to `DEBUG` as we do with other API driven errors. Internal errors (rest codes >=500) are logged as WARN.

When unzipping a plugin zip, the zip entries are resolved relative to
the directory being unzipped into. However, there are currently no
checks that the entry name was not absolute, or relatively points
outside of the plugin dir. This change adds a check for those two cases.
This adds methods and tests to ScriptSortBuilder that
makes it implement NamedWritable and adds the fromXContent
method needed to read itseld from xContent.
This commit adds fields bytes_recovered and files_recovered to the cat
recovery API. These fields, respectively, indicate the total number of
bytes and files recovered. Additionally, for consistency, some totals
fields and translog recovery fields have been renamed.
Closes#17064
