Description

Impala defines, populate, and process several TBLPROPERTIES through Frontend and Backend code. In Frontend code, the property keys are scattered, usually  with prefix TBL_PROP_*. In Backend code, there is a code in workload-management.cc that set table properties for query log table.

Putting all of those TBLPROPERTIES key in single common place, such as a thrift definition, will help developer in documenting and tracing how Impala set and process tables with certain properties.
