This patchset migrates: query_all_directly_granted, query_all,
get_attribute, query_attribute_for_all functions to use cache
instead of doing CQL queries. It also includes some preparatory
work which fixes cache update order and triggering.
Main motivation behind this is to make sure that all calls
from service_level_controller::auth_integration are cached,
which we achieve here.
Alternative implementation could move the whole auth_integration
data into auth cache but since auth_integration manages also lifetime
and contains service levels specific logic such solution would be
too complex for little (if any) gain.

Backport: no, not a bug
