`LoadPartitions` does not guarantee the current target has loading
partitions if there are some partitions already loaded before.
This PR check current target contains the partition to load when
advancing loading percentage to 100.

when try to do stopping balance for stopping query node, balancer will
try to get node list from replica.GetNodes, then check whether node is
stopping, if so, stopping balance will be triggered for this replica.
after the replica refactor, replica.GetNodes only return rwNodes, and
the stopping node maintains in roNodes, so balancer couldn't find
replica which contains stopping node, and stopping balance for replica
won't be triggered, then query node will stuck forever due to
segment/channel doesn't move out.

cause balance channel will stuck until leader view catch up the current
target, then start to unsub the old delegator. which make sure that the
new delegator can provide search before release old delegator. but
another logic in segment_checker skip loading segment during balance
channel. so during balance channel, if query node crash, new delegator
can't catch up target forever, then stuck forever.
This PR remove the rule that skip loading segment during balance channel
to avoid the logic dead lock here.

sync distribution by rpc will also call loadSegment/releaseSegment,
which may cause all kinds of concurrent case on same segment, such as
concurrent load and release on one segment.
This PR add leader_checker which generate load/release task to correct
the leader view, instead of calling sync distribution by rpc
