Fix access rules tempest v2 client

_get_access_action_name() purpose is to get proper action name
based on microversion, currently works only for allow_access,
but is used by list_access_rules() and delete_access_rule() as well.

This change fixes the method to work for all access rules methods.

This change also improves tempest tests to use both V1 and V2 client
in access rules tests.
