(maint) fixing up the nxapi port defaults
(maint) fixing up the nxapi port defaults

Previously it was using a default of `22` for the NXAPI port, and since it was never previously used it was fine as it would default to `80` in node_utils, with a recent change to node_utils it now makes use of the `port` value.

If you wish to use an alternative port, in the beaker hosts file under ssh you can specify a port to use:

```
ssh:
      user: admin
      password: admin
      port: 8280
      auth_methods:
        - password
```
