Dropping table does not remove role-based whitelist on that table

[etedpet]

When using Role Based Whitelisting with the following setup:

Given user/role kalle_wl wihch is granted all permissions to table ks.test:
cassandra@cqlsh> grant all on TABLE ks.test TO kalle_wl;

And the user/role is whitelisted for the ks.test table:
cassandra@cqlsh> ALTER ROLE kalle_wl WITH OPTIONS = { 'GRANT AUDIT WHITELIST FOR ALL' : 'data/ks/test' };

Gives the following permissions:

cassandra@cqlsh> list all PERMISSIONS of kalle_wl;
 role     | username | resource        | permission
----------+----------+-----------------+------------
 kalle_wl | kalle_wl | <table ks.test> |      ALTER
 kalle_wl | kalle_wl | <table ks.test> |       DROP
 kalle_wl | kalle_wl | <table ks.test> |     SELECT
 kalle_wl | kalle_wl | <table ks.test> |     MODIFY
 kalle_wl | kalle_wl | <table ks.test> |  AUTHORIZE

Gives the role options:

cassandra@cqlsh> list roles;
 role      | super | login | options
-----------+-------+-------+--------------------------------------------------------------------------
 cassandra |  True |  True |                                                                        {}
  kalle_wl | False | False | {'AUDIT WHITELIST ON data/ks/test': 'ALTER,DROP,SELECT,MODIFY,AUTHORIZE'}

When the table is dropped:
cassandra@cqlsh> DROP TABLE ks.test ;

Then the permission for that table is removed:

cassandra@cqlsh> list all PERMISSIONS of kalle_wl ;
 role | resource | permissions
------+----------+-------------

BUT the whitelist-data for that user is not removed:

cassandra@cqlsh> list roles;
 role      | super | login | options
-----------+-------+-------+--------------------------------------------------------------------------
 cassandra |  True |  True |                                                                        {}
  kalle_wl | False | False | {'AUDIT WHITELIST ON data/ks/test': 'ALTER,DROP,SELECT,MODIFY,AUTHORIZE'}

-> This could lead to whitelist "issues" if another table is created with the same name... The new table will immediately be whitelisted, which might not be the intent.
