needs separate guice module.

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

Remove unused builders for union types generated by yangtools

Generated builders are not used in the runtime.

Starting from ODL boron, strings that represent union types,
are processed according to YANG RFC, that is in the order
they are specified in the "type" statement,
unitl a match is found. That makes
builders for union types obsolete.

Make ip-version mandatory for all ACEs

- ip-version was mandatory only when mixing l2/l3 rules in one ACE
(vpp api limitation). It needs to be provided also in case of
ACEs that define l3 only rules (we allow mixing ip4/ip6 ACEs
in one list).

- updates postman collestion with example of L4 only acl
