Downgrade libp2p to 0.17.0

[arajasek]

This is to unblock the Lotus 1.15.0 release until libp2p/go-libp2p#1267 (comment) this is complete. We hope to upgrade to 0.18.0 in Lotus 1.15.1.

I am making it clear that i will not be redoing that work again; it is your responsibility now.

@vyzo Redoing what, specifically? We're not dropping this from master, just the February release branch.
