Previously, the `libp2p-ping` module came with a policy to close a connection after X failed pings. This is only one of many possible policies on how users would want to do connection management.
We remove this policy without a replacement. If users wish to restore this functionality, they can easily implement such policy themselves: The default value of `max_failures` was 1. To restore the previous functionality users can simply close the connection upon the first received ping error.
In this same patch, we also simplify the API of `ping::Event` by removing the layer of `ping::Success` and instead reporting the RTT to the peer directly.

In the libp2p specs, the only handshake pattern that is specified is the XX handshake. Support for other handshake patterns can be added through external modules. While we are at it, we rename the remaining types to following the laid out naming convention.
The tests for handshakes other than XX are removed. The handshakes still work as we don't touch them in this patch.

Due to cargo's feature unification, a full build of our workspace doesn't actually check whether the examples compile as standalone projects.
We add a new CI check that iterates through all crates in the `examples/` directory and runs a plain `cargo check` on them. Any failure is bubbled up via `set -e`, thus failing CI in case one of the `cargo check` commands fails.
To fix the current failures, we construct a simple TCP transport everywhere where we were previously using `development_transport`. That is because `development_transport` requires `mplex` which is now deprecated.
