Minor Description
Improve the error messages thrown by REFRESH TABLE METADATA command:
In the first case below, the error is maprfs.abc doesn't exist. It should throw a Object not found or workspace not found. It is currently throwing a non helpful message;
0: jdbc:drill:> refresh table metadata maprfs.abc.`my_table`;
--------------------+
ok summary
--------------------+
false Error: null
--------------------+

In the second case below, it says refresh table metadata is supported only for single-directory based Parquet tables. But the command works for nested multi-directory Parquet files.
0: jdbc:drill:> refresh table metadata maprfs.vnaranammalpuram.`rfm_sales_vw`;
-----------+
ok summary

false Table rfm_sales_vw does not support metadata refresh. Support is currently limited to single-directory-based Parquet tables.
