when i have created pbb tag rewrite, there is no option how to check what is set via vpp terminal or vat. please add some dump command to see settings. we need this for testing if pbb was created correctly or not

example of pbb tag rewrite:
set interface l2 pbb-tag-rewrite vxlan_tunnel0 push dmac 00:50:56:af:9a:2e smac 00:50:56:af:03:16 b_vlanid 1234 s_id 1111

also it would be great to have some details in trace log to see when pbb tag rewrite was done. there is small info when pbb header is added, but no info when header was removed
