This process prevents stale authorization data from being used.
If any authorization data for an account is changed at runtime, such as
adding or removing roles and/or permissions, the subclass implementation
of AccountStoreRealm should clear the cached AuthorizationInfo for that
account through this method. This ensures that the next call to
get_authorization_info(PrincipalCollection) will acquire the account's
fresh authorization data, which is cached for efficient re-use.

:param identifier: the identifier of a specific source, extracted from
                   the SimpleIdentifierCollection (identifiers)
