HC2VPP-288 - add SRv6 module (writers only)

Changes:
- add new module for SRv6
- add models for SRv6 configuration:
  from https://datatracker.ietf.org/doc/draft-raza-spring-srv6-yang/
   - hc2vpp-ietf-srv6-base@2018-03-01.yang
   - hc2vpp-ietf-srv6-static@2018-03-01.yang
   - ietf-srv6-types@2018-03-01.yang
- implements Configuration of local sids and their end functions.
- implements support for FIB table management (HC2VPP-345)

Models hc2vpp-ietf-srv6-base and hc2vpp-ietf-srv6-static
are changed (HC2VPP-332):
 - imports for routing models (HC2VPP-298)
 - presence in end function containers was added to fix
   mandatory child verification if parent container is not present
