    [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
