[aclorch] add generic AclOrch::updateAclRule() method (#1993)
- What I did I added generic AclOrch::updateAclRule() implementation. This implementation takes a newly constructed shared_ptr<AclRule> provided by the user, calculates a difference between priority, matches and actions and calls sai_acl_api->set_acl_entry_attribute() for those attributes that were changed. The derivatives of AclRule can customize the behaviour of AclRule::update(const AclRule& updatedRule) by polymorphic override, although in that case the derivative needs dynamic_cast the updatedRule to a concrete derivative type. Added unit test to cover update scenario. Currently this new API is not used by any clients nor handling ACL_RULE table updates. This API will be used by PBH ACL rule update flow. - Why I did it To support the scenario for updating PBH ACL rule in the future. - How I verified it Temporary changed the ACL_RULE table update to leverage this new API and tested updates through CONFIG_DB and unit test coverage.
