if compaction/gc happens, load collection may stuck due to

issue: #36293#36242
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

those test case use search to verify replica's status, but if the search
gap is 1s, the node down's effect may be fixed up by balance.
This PR remove the 1 second gap between search operation.

After collection loaded, if we need to increase/decrease collection's
replica, we need to release and load it again.
milvus offers 4 solution to update loaded collection's replica, this PR
aims to dynamic change the replica number without release, and after
replica number changed, milvus will execute load replica or release
replica in async, and the replica loaded status can be checked by
getReplicas API.
Notice that if set too much replicas than querynode can afford，the new
replica won't be loaded successfully until enough querynode joins.

issue: #34595
When consuming insert data on the delegator node, QueryCoord will move
out some sealed segments to manage its memory usage. After the growing
segment gets flushed, some sealed segments from other workers will be
moved back to the delegator node. To avoid the frequent movement of
segments, we estimate the maximum growing row count and preserve a
fixed-size memory in the delegator node.

This PR introduce two database level props:
1. database.replica.number
2. database.resource_groups
User can set those two database props by AlterDatabase API, then can
load collection without specified replica_num and resource groups. then
it will use database level load param when try to load collections.

grpcclient's `call` func return a unrecoverable error, then the caller's
retry policy also breaks due to this unrecoverable error.
This PR introduce `retry.Handle`, the new func use `func() (bool,
error)` as input parameters, which return `shouldRetry` directly, to
avoid grpcclient return a unrecoverable error
