Upgrade microVersionId to timestamp-ordered format and add isReplica

[maeldonn]

Replace the random 8-byte hex microVersionId with a 20-character timestamp-ordered identifier matching the versionId scheme, and add encode/decode/compare helpers in a new MicroVersionID module. Add an optional isReplica flag to ReplicationInfo to distinguish replica writes from user writes, enabling cascaded CRR.

Issue: ARSN-578

• Breaking API change: updateMicroVersionId() now requires a replicationGroupId argument, which will break all existing callers in downstream repos (CloudServer, Backbeat, etc.). Coordinate updates or consider an optional parameter with a fallback.
  • Make the parameter optional with a random default, or ensure all consumers are updated in the same release cycle.
• updateMicroVersionId JSDoc says @return itself but the method body has no return this statement.
  • Add return this; for consistency with other ObjectMD setters.

LGTM

The changes are well-structured: the new MicroVersionId module correctly mirrors the VersionId timestamp-ordering scheme with its own isolated sequencing state, the isReplica flag is cleanly additive and backward compatible, and the test coverage is thorough (uniqueness, ordering, encode/decode round-trip, compare, padding/truncation).

updateMicroVersionId is documented with @return itself but doesn't actually return this, unlike every other setter/updater in the class (e.g. setReplicationIsReplica, setReplicationIsNFS). Since this method is being rewritten anyway, this is a good opportunity to fix the mismatch.

Suggested change

	}
	updateMicroVersionId(replicationGroupId: string) {
	this._data.microVersionId = MicroVersionIdUtils.generate(replicationGroupId);
	return this;
	}

• updateMicroVersionId JSDoc says @return itself but the method doesn't return this, breaking the chaining convention used by all other setters in ObjectMD. Since the method is being rewritten, add return this;.

Breaking API change: updateMicroVersionId() now requires a replicationGroupId argument. All downstream callers (CloudServer, Backbeat, etc.) that invoke this method without arguments will fail at compile time. Ensure coordinated updates across dependent repos.

LGTM — one breaking change to flag:

- updateMicroVersionId() signature changed to require a replicationGroupId parameter — downstream callers (CloudServer, Backbeat) must be updated in lockstep

The new MicroVersionId module, isReplica field, and timestamp-ordered format all look correct. Backward compatibility for existing stored metadata (old 16-char random hex microVersionIds) is preserved since getMicroVersionId() returns the raw value and _updateFromParsedJSON copies it as-is.

@return itself in the JSDoc, but the method never returns this. Every other setter in this class (setReplicationIsNFS, setReplicationIsReplica, etc.) returns this for chaining. Since this PR is already editing the method and its JSDoc, either add the missing return this; or drop the @return tag.

Suggested change

	}
	updateMicroVersionId(replicationGroupId: string) {
	this._data.microVersionId = MicroVersionIdUtils.generate(replicationGroupId);
	return this;
	}

• updateMicroVersionId JSDoc says @return itself but the method body has no return this — either add the return or remove the tag (see inline suggestion)
• Note: updateMicroVersionId() now requires a replicationGroupId parameter — this is a breaking API change for all downstream callers (CloudServer, Backbeat, etc.). Ensure consumers are updated in lockstep.

@return itself but the method has no return this; statement — it returns void. Since this JSDoc was updated in this PR, either add return this; for consistency with the other setters, or remove the stale @return tag.

Suggested change

	}
	* @return itself
	*/
	updateMicroVersionId(instanceId: string, replicationGroupId: string) {
	this._data.microVersionId = VersionIDUtils.generateVersionId(instanceId, replicationGroupId);
