Provide a dataclass abstraction for clients and other objects

[nickovs]

Currently the representation of clients in unificontrol is just the raw data that comes back from the underlying API. In a comment on another issue @wolph suggested that it would be useful to have an abstraction that represents clients as their own data objects and provide a higher level API for manipulating them.

[wolph]

For Python 3.6 there's a backport available so that's easily fixed: https://pypi.org/project/dataclasses/
The requirement would be:

dataclasses; python_version < '3.7'

Another question would be how this new API would be exposed. The way I see it there are a few options:

1. Add an option to client so client.list_clients() returns this object when the new API is enabled
2. Add a parameter to methods such as client.list_client() so it returns the new style
3. Add a new method for this so that client.clients would be a collection class that is both iterable and subscriptable using something like client.clients[mac_address].
4. Add a dict api to the dataclasses to maintain backwards compatibility

My vote would be option 3, but that's your decision :)

Using these we can create a high-level API that could work something like this:

fixed_hosts = dict(...)

for client in api.clients:
    fixed_host = fixed_hosts.get(client.mac)
    if not fixed_host:
        continue

    client.name = fixed_hostname.name
    client.fixed_ip = fixed_hostname.ip

# Or:
for mac, fixed_host in fixed_hosts.items():
    api.clients[mac].name = fixed_host.name
    api.clients[mac].fixed_ip = fixed_host.ip
