feat(client): client can now be configured without config files

[sg-s]

problem

We want to be able to use the client in contexts where:

• we don't have write access to the filesystem
• where the config file doesn't exist
• where we want to use the client to connect to different resources than specified in the config file
• we don't want to make any authentication requests, we already have a hot token

solution

to solve all these problems, it should be possible to do something like this:

from deeporigin.managed_data.client import DeepOriginClient
client = DeepOriginClient(api_url="foo", org_id="bar")
client.authenticate(token="token")
