New checks:

• NetworkThroughput measures network interface rx/tx throughput.
• DockerContainerStatus checks if docker containers are running (and healthy)

Other new features:

• New error_recover_action that is triggered on transitions from the error state back to good/bad.
• The TLS backend can be selected with features native-tls, rustls-tls and default-tls (which is equivalent to native-tls).
  • Note: You have to specify --no-default-features to disable the default-tls feature if you like to use rustls-tls.

Notes

• Documentation has been reworked.
• Checks are now triggered with a random delay when they are triggered for the first time to avoid CPU and I/O spikes (see #55 for details).
• There is a new optional feature http to enable/disable the Webhook action (and the required dependencies).
• There is a new optional feature smtp to enable/disable the Email action (and the required dependencies).

The ARMv7 Docker images does not build in the GitHub Action for some reason.
