Clean up after Client deletion, finish cleaning up after Profile deletion. 6f473576c6ae started cleaning up after Profiles when they're deleted, but didn't clean up the Clients created by that Profile. This fixes that, and also fixes a BUG note about cleaning up after a Client when it's deleted. Extend the authorizationCodeStore to have a deleteAuthorizationCodesByClientID method that will delete the AuthorizationCodes that have been granted by the Client specified by the passed ID. We also implemented this in memstore and postgres, so tests continue to pass. Extend the clientStore to have a deleteClientsByOwner method that will delete the Clients that were created by the Profile specified by the passed ID. We also implemented this in memstore and postgres, so tests continue to pass. Extend the clientStore to have a removeEndpointsByClientID method that will delete the Endpoints that belong(ed) to a the Client specified by the passed ID. We also implemented this in memstore and postgres, so tests continue to pass. Extend the tokenStore to have a revokeTokensByClientID method that will revoke all the Tokens that were granted to the Client specified by the passed ID. We also implemented this in memstore and postgres, so tests continue to pass. When listing Clients by their owner, allow setting the num argument (which controls how many to return) to 0 or lower, and using that to signal "return all Clients belonging to this owner", instead of paging. This is useful when deleting the Clients belonging to a Profile as part of the cleanup after deleting the Profile. Create a cleanUpAfterClientDeletion helper function that will delete the Endpoints and AuthorizationCodes belonging to a Client, and revoke the Tokens belonging to a Client, as part of cleaning up after a Client has been deleted. Add a check in the handler for listing Clients owned by a Profile to disallow the num argument to be lower than 1, because the API should be forced to page. Call our cleanUpAfterClientDeletion once the Client has been deleted in the appropriate handler. Fill out our Context with new methods to wrap all the new methods we're adding to our *Stores. In cleanUpAfterProfileDeletion, obtain a list of clients belonging to the owner, use our new DeleteClientsByOwner method to remove all of them, and then use the list to run our new cleanUpAfterClientDeletion function to clear away the final remnants of a Profile when it's deleted.
