net-mgmt/py-pynxos: Deprecate/Set to expire
- Upstream is inactive since +7 years, the package was used by py-napalm for a little while until it was replaced by py-nxapi-plumbing. There are no more consumers left in the tree.
- Set a fairly short EXPIRATION_DATE because the Python stack is quite outdated - for example, py-future is still being used [1].
