after qn recover, delegator may be loaded in new node, after all segment
has been loaded, delegator becomes serviceable. but delegator's target
version hasn't been synced, and if search/query comes, delegator will
use wrong target version to filter out a empty segment list, which
caused empty search result.
This pr will block delegator's serviceable status until target version
is synced

This PR enable balance on querynode with different mem capacity, for
query node which has more mem capactity will be assigned more records,
and query node with the largest difference between assignedScore and
currentScore will have a higher priority to carry the new segment.

querycoord will notify proxy to update shard leader cache after
delegator location changes, but during querynode's failure recovery,
some delegator may become unserviceable due to lacking of segments, and
back to serviceable after segment loaded, so we also need to notify
proxy to invalidate shard leader cache when delegator serviceable state
changes.
This PR will maintain querynode's serviceable state during heartbeat,
and notify proxy to invalidate shard leader cache if serviceable state
changes.

pr #32814 introduce the compatible issue, when upgrade to milvus latest,
the query coord may skip update dist due to the lastModifyTs doesn't
changes. but for old version querynode, the lastModifyTs in
GetDataDistritbuionResponse is always 0, which makes qc skip update
dist. then qc will keep retry the task to watch channel again and again.
this PR add compatible with old version querynode, when lastModifyTs is
0, qc will update it's data distribution.
