this PR only use better compression level for proto msg which is larger
than 1MB, and use a lighter compression level for smaller proto msg,
which could get a better latency in most case.
this PR could reduce the latency from 22.7s to 4.7s with 10000
collctions and each collections has 1000 segments.

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.
