HONEYCOMB-304: provide separate guice module for ietf-acl implementation

Current IETF-ACL implementation is using vpp-classfier.
In the future, acl implementation based on acl plugin is going to be
supported. Current implementation is going to be deprecated, then removed.
In order to switch between acl implementations, ietf-acl configuration
needs separate guice module.

After fixing nested augmentation support (HONEYCOMB-302), current
implementation can be moved to separate hc2vpp module (HONEYCOMB-308).
