p2p: rate limit outgoing p2p http connections

[algorandskiy]

Summary

Make P2PNetwork to produce rate limiting outgoing HTTP clients. There are some some movements into subpackages to allow both network, p2p, peerstore to use some utilities/functionality.

• addr.go -> network/addr
• phonebook -> network/phonebook (to make peerstore's interface compatible with phonebook)
• dialer, ratelimit transport -> network/limitcaller

Had to modify phonebook interface to accept both string and p2p.peer.AddrInfo (alternative is to marshal AddrInfo to bytes, cast and unmarshal but it is kind of the same). Plus, the current peerstore's implementation of Phonebook interface uses "host:port" as peerID and works only with "host:port" addresses and not with any kind of p2p addresses so it requires some change anyway. This is a first step.

Test Plan

Added a unit test.
