before all queries complete during rebalance

[ASTERIXDB-2246][STO] Ensure Metadata Cache Updated on Rebalance
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
- Ensure metadata cache is updated to the target
dataset by commiting the transaction before
downgrading the write lock. This prevents waiting
readers from reading a stale cache that points
to the source dataset that will be dropped.
