new models:
- hc2vpp-oc-srte-policy@2017-09-18.yang
  (ietf draft for srte-policies)
- vpp-oc-srte-policy@2018-05-14.yang
  (augments oc-srte-policy model with VPP specific configuration)
- policy-context@2018-06-07.yang
  defines policy contexts for policies and candidate paths

new features:
- adds support for writing/reading SRv6 policies
- adds support for writing/reading L2 steering
- adds support for writing/reading L3 steering
- implements support for FIB table management (HC2VPP-345)
