For cases where we have very high values set to permissions_cache validity and
update interval (E.g.: 1 day), whenever a change to permissions is made it's
necessary to update scylla config and decrease these values, since waiting for
all this time to pass wouldn't be viable.
This patch adds an API for resetting the authorization cache so that changing
the config won't be mandatory for these cases.
Usage:
$ curl -X POST http://localhost:10000/authorization_cache/reset
