Check sort key to see if it is an allowed field

[Ruby Loo]

We aren't checking the value for the sort key in a node-list operation. We allow to sort on a field even if that field is not available in the specified API version.

The patch addresses sort key when getting lists for node, port groups, and ports. (It wasn't needed for chassis since it doesn't have any new fields guarded by API microversions.)

    Check if sort key is allowed in API version

    This checks the sort key, to make sure the specified field
    is allowed/available in the specified API microversion.
    If it is not allowed, a 406 HTTP status is returned.

    This affects requests to get lists of nodes, port groups,
    and ports.
