- based on previously submitted schema and validation, can add a TAP
with host netns, bridge and MTU.
- detect diffs in __tap_has_diff(), used to prune TAPs that must change
- add prune_taps() and create_taps() in the reconciler
- add Dumper() logic to emit YAML config for TAPs
- Move tap_is_lcp() into the VPPApi() class, so it can be reused
Add lots of test cases in intest/*.yaml and example.yaml - full
regression and integration and unit/YAML tests pass on this change.
