This commmit implements DESCRIBE DATABASE [FORMATTED|EXTENDED] <db_name>.
Without FORMATTED|EXTENDED this statement only prints database's location and
comment. With FORMATTED|EXTENDED it will output all the properties of the database
(e.g. OWNER and PARAMETERS). Currently we only retrieve privileges stored in
hive metastore.
This commit also implements DESCRIBE EXTENDED <table>, which is the same
as DESCRIBE FORMATTED <table> for consistency purpose.
