* nxos_linkagg: `group` type mismatch causes idempotency failure
* `group` values need to be cast; e.g.
```
want = {'group': '20'}
have = {'group': 20}
```
* Found with N7K `sanity` test
* nxos_linkagg: change group param type to str
* nxos_interface vlan and port-channel idempotence fix for mtu
* Fix MTU reconfiguration at each execution
* nxos_interface port-channel idempotence fix for mode (#44248)
* Fix trunk mode idempotence for port-channel
* Gather ethernet and port-channel code for mode management
* nxos_linkagg port-channel idempotence fix for channel-group's mode
The regex to retrieve channel-group's mode is not enough accurate.
Therefore, the swhitchport mode was matched instead of the
channel-group's mode.
* This fix add accuracy to match the right configuration command
* Add support for switchport mode dot1q-tunnel in nxos_interface
* Fix layer reconfiguration at each execution
