Here the logic to update quota can be removed and added with a TODO. Since the way to update quota will be changed in #1489, we will no longer rely on volume usedBytes and will no longer use LongAdder. Calculate quotaReleased logic can be retained.

What changes were proposed in this pull request?
When OM receives truncate(key, newLength),in the keyTable, OM deletes the blocks which are fully truncated, and updates the block length which is partially truncated, then return success to client.
Ozone client read key according to the block length got from OM, which has already been implemented.
So, with this PR, Ozone client can read the truncated key with newLength, when the truncate operation returns success.
