URL: https://github.com/apache/hive/pull/2065
### What changes were proposed in this pull request?
Currently, the Workload management move trigger kills the query being moved
to a different pool if destination pool does not have enough capacity. This PR
introduces a "delayed move" configuration which lets the query run in the
source pool as long as possible, if the destination pool is full. It will
attempt the move to destination pool only when there is claim upon the source
pool. If the destination pool is not full, delayed move behaves as normal move
i.e. the move will happen immediately.
### Why are the changes needed?
For better utilization of cluster resources.
### Does this PR introduce _any_ user-facing change? Yes
### How was this patch tested? Unit test
