Dimitris Tsirogiannis fdb90ed753 CDH-23206: Impala support for column-level authorization (part 1)
This commit adds partial support for column-level authorization in
Impala using the Sentry Service. The following changes are included:
* Added support for parsing and analyzing GRANT/REVOKE statements with column-level
  privileges. The supporting syntax is:
  - GRANT SELECT (<col_names>) ON TABLE <table_name>
    TO [ROLE] <role_name> [WITH GRANT OPTION]
  - REVOKE [GRANT OPTION FROM] SELECT (<col_names>) ON
    TABLE <table_name> FROM [ROLE] <role_name>
* Added support for storing column-level privileges in the Catalog Service and updating
  the Sentry Service when GRANT/REVOKE statements are executed.
* Modified the SHOW GRANT ROLE statement to include information about
  column-level privileges.

Subsequent patches will add support for enforcing column-level
privileges in SQL queries and other statements.
