Don't close connection if ping protocol is unsupported by remote. Previously, a failed protocol negotation for ping caused a force close of the connection. As a result, all nodes in a network had to support ping. To allow networks where some nodes don't support ping, we now emit PingFailure::Unsupported once for every connection on which ping is not supported.

In case you want to stick with the old behavior, you need to close the connection manually on PingFailure::Unsupported.

Fixes #2109. Also see PR 2149.
Rename types as per discussion 2174. Ping has been renamed to Behaviour. The Ping prefix has been removed from various types like PingEvent. Users should prefer importing the ping protocol as a module (use libp2p::ping;), and refer to its types via ping::. For example: ping::Behaviour or ping::Event.

Ensure the outbound ping is flushed before awaiting the response. Otherwise the behaviour depends on implementation details of the stream muxer used. The current behaviour resulted in stalls with Mplex.
