Improve connection check with peers by retrying ping on failures (#330)

* Improve connection check with peers by retrying ping on failures

* Use DEFAULT_PING_INTERVAL in cli

* Log only error message

* Add config option to pass peer id file path

* Finish retrying pings before connection check interval duration

* Handle duplicate connections to relay nodes

* Increase default max dial retries from one relay to another

* Update connection manager config for relay nodes

* Use debug for logs in relay node
