Remove py-libp2p-daemon

pypi rejects releases with this kind of dependency:

https://github.com/libp2p/py-libp2p/blob/811cd7813a74ef55110e1ae09dac7028c6caa0a4/setup.py#L12-L13

I had to manually remove that line from the tagged commit before releasing.

Some options:

• remove it (maybe it’s cruft that is not necessary anymore?)
• inline it (maybe it’s small enough that it’s worth just bringing into this repo)
• do a proper release of py-libp2p-daemon

just to chime in here, i think having py-libp2p be the “foundational” package here (possibly used by p2pclient) makes the most sense – while the extent to which we make affordances to libp2p towards this end is subjective, i’d think its worthwhile exploring the interop tests to see if we can’t accomplish them another way – for example, a full interop suite would also involve rust-libp2p, nim-libp2p and js-libp2p alongside go-libp2p where we won’t have client bindings (easily)

In this sense, does it make sense if we let p2pclient stay in the tests(or extract to another directory) and move it into tox dependency for now, and remove it when the codebase becomes more stable?

I think the best solution then might be to only install p2pclient in the specific tox environment that runs these integration tests, something like:

tox.ini

[testenv:py37-interop]
deps = p2pclient
