[HUDI-554] Cleanup package structure in hudi-client (#1346)

- Just package, class moves and renames with the following intent
 - `client` now has all the various client classes, that do the transaction management
 - `func` renamed to `execution` and some helpers moved to `client/utils`
 - All compaction code under `io` now under `table/compact`
 - Rollback code under `table/rollback` and in general all code for individual operations under `table`
 - `exception` `config`, `metrics` left untouched
 - Moved the tests also accordingly
 - Fixed some flaky tests
