+ Add ability to inherit server sockets on restart
Add auth token support to App::Status
Add ability to restart by reexecing and pumactl to use it
This allows all existing requests to finish, but does not keep the same
socket alive across the exec, so this is not a graceful as it could be.
Add App::Status rack app to control a server
Puma::App::Status is a rack app that can be used to control the current
server. It allows a server to be queried remotely programmaticly.
