[topo_m0] Add new topo for mgmt tor router (#6208)

What is the motivation for this PR?
For mgmt tor router, both testing methodology and physical wiring pattern are quite different with existing T0/T1/ topo. Adding this topo can let us filter unrelated test cases from mgmt network.

How did you do it?
Add a new topo (inherit from t0-52)
Enhance topo config and topo_facts for including interfaces
Enhance minigraph templates to support generate minigraph for this new topo
How did you verify/test it?
Generate minigraph and deploy to DUT.
Use ./testbed-cli.sh deploy-mg to gen&deploy minigraph with new topo m0 successfully,
All the related configuration are correct pushed to DUT after deploy.
