nit: We can remove _doc mapping as mapping types are deprecated.

After update & Delete i'm asserting the equality of each doc id not just counts.

…aining segment replication changes (#4243)

* [Segment Replication] Checkpoint Replay on Replica Shard (#3658)

* Adding Latest Recevied checkpoint, replay checkpoint logic along with tests

Signed-off-by: Rishikesh1159 <rishireddy1159@gmail.com>

* [Segment Replication] Wire up segment replication with peer recovery and add ITs. (#3743)

* Add null check when computing max segment version.

With segment replication enabled it is possible Lucene does not set the SegmentInfos
min segment version, leaving the default value as null.

Signed-off-by: Marc Handalian <handalm@amazon.com>

* Update peer recovery to set the translogUUID of replicas to the UUID generated on the primary.

This change updates the UUID when the translog is created to the value stored in the passed segment userdata.
This is to ensure during failover scenarios that the replica can be promoted and not have a uuid mismatch with the value stored in user data.

* Wire up Segment Replication under the feature flag.

This PR wires up segment replication and adds some initial integration tests.

* Disable shard idle with segment replication. (#4118)

This change disables shard idle when segment replication is enabled.
Primary shards will only push out new segments on refresh, we do not want to block this based on search behavior.
Replicas will only refresh on an externally provided SegmentInfos, so we do not want search requests to hang waiting for a refresh.

* Fix OngoingSegmentReplications to key by allocation ID instead of DiscoveryNode.

This change fixes segrep to work with multiple shards per node by keying ongoing replications on
allocation ID.  This also updates cancel methods to ensure state is properly cleared on shard cancel.
