Flesh out the parse_class?

[Jaymon]

Both morp and prom have similar Connection classes. Would it be worth fleshing out the base class with the base functionality here and then letting prom and morp extend it?

I do some variation of this in morp, prom, and caches:

        d = {
            "caches.interface.Redis": set(["redis"]),
        }

        kv = v.lower()
        for interface_name, vals in d.items():
            if kv in vals:
                ret = interface_name
                break

It would be great to make this natively supported
