In some cases the retention leases can return null, causing a
`NullPointerException` when waiting for no followers.
This wraps those so that no NPE is thrown.
Here is an example failure:
```

Fix#40348
(cherry picked from commit e3070615000228c283d17ce8d182b44f1450a5d5)
Replicated closed indices can't be indexed into or searched, and therefore don't need a shard with
full indexing and search capabilities allocated. We can save on a lot of heap memory for those
indices by not allocating a mapper service and caching infrastructure (which preallocates a constant
amount per instance). Before this change, a 1GB ES instance could host 250 replicated closed
metricbeat indices (each index with one shard). After this change, the same instance can host 7300
replicated closed metricbeat instances (not that this would be a recommended configuration). Most
of the remaining memory is in the cluster state and the IndexSettings object.
Previously, `getTime(colIdx/colLabel)` and
`getObject(colIdx/colLabel, java.sql.Time.class)` methods were computing
the time from a `ZonedDateTime` by applying day in millis modulo on the epoch millis
of the `ZonedDateTime` object. This is wrong as we need to keep the time
related fields at the timezone of the `ZonedDateTime` object and just
set the date info to the epoch date (01/01/1970).
Additionally fixes a testing issue as the original timezone id is converted
to an offset string when parsing the response from the server.
* Document MATCH and QUERY function predicates.
* Polish the functions pages and add a list of functions to the main Functions & Operators page.

Currently the TransportMessageListener is applied and used in the
Transport class. However, local requests and responses never make it to
this class. This PR moves the listener add/remove methods to the
TransportService. After this change the Transport can only have one
listener set with it. This one listener is the TransportService, which
will then propogate the events to the external listeners.
Additionally this commit back ports #40237

create and use unique, deterministic document ids based on the grouping values.
This is a pre-requisite for updating documents as well as preventing duplicates after a hard failure during indexing.
Ensure that there is at least a 1s delay between the time that state
is persisted by each of the two jobs in the test.
Model snapshot IDs use the current time in epoch seconds to
distinguish themselves, hence snapshots will be overwritten
by another if it occurs in the same 1s window.
Closes#40347
To avoid having to specify each spec by hand (which can miss specs to be
added), the test infrastructure now performs classpath discovery so that
each spec added, is automatically considered.

Right now, the stats API only provides refresh metrics regarding
internal refreshes. This isn't very useful and somewhat misleading for
cluster administrators since the internal refreshes are not indicative
of documents being available for search.
In this PR I added a new metric for collecting external refreshes as
they occur and exposing them through the stats API. Now, calling an
endpoint for stats will yield external refresh metrics as well.
Relates #36712
Previously, `getDate(int columnIdx)/getDate(String columnLabel)` and
were using legacy`java.util.Calendar` instead of the the `java.time.*`
classes to reset to the start of day. This resulted in different results
for certain timestamps and timezones when calling
`getDate(col)` vs`getObject(col, java.sql.Date)`
Now only the methods (that must be implemented due to the JDBC spec)
`getDate(int columnIdx, Calendar cal)/getDate(String columnLabel, Calendar cal)`
are still using the `java.util.Calendar` for those conversion.
The same change was applied to
`getTime(int columnIdx)/getTime(String columnLabel)`
and
`getTimestamp(int columnIdx)/getTimestamp(String columnLabel)`

In some cases, a request to perform a retention lease action can arrive
on a primary shard before it is active. In this case, the primary shard
would not yet be in primary mode, tripping an assertion in the
replication tracker. Instead, we should not attempt to perform such
actions on an initializing shard. This commit addresses this by not
returning the primary shard in the single shard iterator if the primary
shard is not yet active.
Previously metric aggregations on date fields would return a double
which caused errors when trying to apply scalar functions on top, e.g.:
```
SELECT YEAR(MAX(date)) FROM test
```

Add a checkpoint service for data frame transforms, which allows to ask for a checkpoint of the
source. In future these checkpoints will be stored in the internal index to
- detect upstream changes
- updating the data frame without a full re-run
- allow data frame clients to checkpoint themselves
* Rewrite Round and Truncate functions to have a slightly different
approach to handling the optional parameter in the constructor. Until now
the optional parameter was considered 0 if the value was missing and the
constructor was filling in this value. The current solution is to have
the optional parameter as null right until the actual calculation is done.
