when call TransferChannel/TransferSegment, querycoord will generate and
submit balance task to scheduler, if segment/channel's task already
exist in scheduler, submit task will failed.
to make TransferChannel/TransferSegment idempotent, we should skip to
submit if task already exist in scheduler.

issue: #36536
query coord use `segmentTaskDeleta/channelTaskDelta` to measure the
executing workload for querynode in scheduler, and we maintains the
`segmentTaskDeleta/channelTaskDelta` by `scheulder.Add(task)` and
`scheduler.remove(task)`, but `scheduler.remove(task)` has been called
in unexpected way, which cause a wrong
`segmentTaskDeleta/channelTaskDelta` value and affect the segment assign
logic, causes segment unbalance.
This PR moves to compute the `segmentTaskDeleta/channelTaskDelta` when
access, to avoid the wrong value affect.

* improved `Column.h` to make the code much more readable and
maintainable, and added detailed comments.
* fixed an issue where `ArrayColumn::NumRows()` always returns 0 when
the mmap backing storage is a file.
* removed unused `ColumnBase` constructors and unnecessary members so we
don't get confused.
* Updated `test_chunk_cache.cpp` to make the tests parameterized: to
test both mmap enabled and disabled. Added sparse field in the test to
add coverage.
* re-enabled test `Sealed::GetSparseVectorFromChunkCache`.
* But 2 other disabled tests `Sealed::WarmupChunkCache` and
`Sealed::GetVectorFromChunkCache` remain disabled, there seems to be
errors. @bigsheeper PTAL.

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: #36426
the old constriant requires only segment on current target can be
balanced, which is wrong, and caused that segment can't be move out from
stopping node, if it's only exist in next target.
by design, stopping balance need to move out all segment on it by
balance task, thus the unfair old constriant should be removed.

issue: #35859
This PR introduce two new param: toleranceFactor and checkRequestNum,
after every checkRequestNum request has been assigned, try to compute
querynode's workload score.
if the diff is less than the toleranceFactor, replica selection policy
will fallback to round_robin, which reduce the average cost to about
500ns.
if the diff is larger than the toleranceFactor, replica selection policy
will compute querynode's score to select the target node with smallest
score in every assigment.
