Anton Kaliaev 2449bf7300 p2p: file descriptor leaks (#3150 )

* close peer's connection to avoid fd leak

Fixes #2967

* rename peer#Addr to RemoteAddr

* fix test

* fixes after Ethan's review

* bring back the check

* changelog entry

* write a test for switch#acceptRoutine

* increase timeouts? :(

* remove extra assertNPeersWithTimeout

* simplify test

* assert number of peers (just to be safe)

* Cleanup in OnStop

* run tests with verbose flag on CircleCI

* spawn a reading routine to prevent connection from closing

* get port from the listener

random port is faster, but often results in
