He Qi updated FLINK-38848:
--------------------------
Description:
For custom catalogs that have access control, read and write permissions can be
different. However, currently Flink always call {{Catalog#getTable}} to look up
the table, no matter it's for read or write.
This PR adds a variant of get{{{}Table{}}} that indicates the required write
privileges. All the write commands will call this new method to look up tables
instead. This new method has a default implementation that just calls
get{{{}Table{}}}, so there is no breaking change.
