Nhat Nguyen e44e34f42a Rename deleteLocalTranslog to createNewTranslog
We introduced a new option `createNewTranslog` in #28181. However, we
named that parameter as deleteLocalTranslog in other places. This commit
makes sure to have a consistent naming in these places.

Nhat Nguyen 82722ebad3 TEST: init unassigned gcp in testAcquireIndexCommit
The global checkpoint should be assigned to unassigned rather than 0. If
a single document is indexed and the global checkpoint is initialized
with 0, the first commit is safe which the test does not suppose.

Replica start peer recovery with safe commit (#28181)
Today a replica starts a peer-recovery with the last commit. If the last
commit is not a safe commit, a replica will immediately fallback to the
file based sync which is more expensive than the sequence based
recovery. This commit modifies the peer-recovery in replica to start
with a safe commit. Moreover we can keep the existing translog on the
target if the recovery is sequence based recovery.

Truncate tlog cli should assign global checkpoint (#28192)
We are targeting to always have a safe index once the recovery is done. 
This invariant does not hold if the translog is manually truncated by 
users because the truncate translog cli resets the global checkpoint to
unassigned. This commit assigns the global checkpoint to the max_seqno
of the last commit when truncating translog. We can only safely do it
because the truncate translog command will generate a new history uuid
for that shard. With a new history UUID, sequence-based recovery between
that shard and other old shards will be disabled.

Fix lock accounting in releasable lock
Releasble locks hold accounting on who holds the lock when assertions
are enabled. However, the underlying lock can be re-entrant yet we mark
the lock as not held by the current thread as soon as the releasable is
closed. For a re-entrant lock this is not right because the thread could
have entered the lock multiple times. Instead, we have to count how many
times the thread has entered the lock and only mark the lock as not held
by the current thread when the counter reaches zero.

Add ability to associate an ID with tasks (#27764)
Adds support for capturing the X-Opaque-Id header from a REST request and storing it's value in the tasks that this request started. It works for all user-initiated tasks (not only search).

Closes #23250

Usage:
```
$ curl -H "X-Opaque-Id: imotov" -H "foo:bar" "localhost:9200/_tasks?pretty&group_by=parents"
{
  "tasks" : {
    "7qrTVbiDQKiZfubUP7DPkg:6998" : {

Do not keep 5.x commits once having 6.x commits (#28188)
Currently we keep a 5.x index commit as a safe commit until we have a
6.x safe commit. During that time, if peer-recovery happens, a primary
will send a 5.x commit in file-based sync and the recovery will even
fail as the snapshotted commit does not have sequence number tags.

This commit updates the combined deletion policy to delete legacy
commits if there are 6.x commits.
