[chore] deprecations for v1.2.0

[justheuristic]

Currently, p2pd has a few unused options (e.g. relay hop limit) that are no longer used. Typically, they were necessary in an older libp2p version but were eventually deprecated by libp2p devs.

To identify thee parameters, check for flags in main.go which state that the option is deprecated.

Why is this issue not in p2pd repo: before we can remove these options, we need to modify hivemind.p2p interface to no longer pass these options to the daemon.
