add a few less used canonical mappings

[itdependsnetworks]

I had this tied to a PR that never got merged, just going back and cleaning up and adding back.

Coverage remained the same at 0.0% when pulling ce01c90 on itdependsnetworks:can_map into 7ffb3fc on napalm-automation:develop.

@itdependsnetworks CI-CD is failing. It looks like one test needs updated in the test data such that it uses the canonical reults.

E           AssertionError: Expected result varies on some keys [{"interface": {"result": "Ethernet1/2", "expected": "eth1/2"}}, {"interface": {"result": "Ethernet1/1", "expected": "eth1/1"}}]

LGTM in principle, but would like to clarify with Kirk a matter of detail.

I like this, just wanted to mention that on IOS at least there's an optional argument canonical_int defaulting to False currently - is this something we'd want on NX-OS as well? My preference would probably be to always use the canonical map, but maybe there are some reasons on the existence of canonical_int arg I'm not aware of. CC @ktbyers

I do not see this anywhere else in the nxos/nxos_ssh code. I can add it if desired.

Let's open that as a separate issue (so this PR doesn't get bogged down). I would guess for backwards compatibility, but it doesn't look like it was fully/consistently implemented.

I would vote always use canonical interface and just get rid of the argument to toggle that off (especially given that it looks like it is currently inconsistently implemented).
