Detailed Description

Installs signal handler which will stop HTTPServer when the user presses Ctrl-C. To be used if HTTPServer is the main process.

Note: Should only be created from the thread invoking HTTPServer::start().

signalReceived() will called to indicate that the specified signal has been received.

signalReceived() will always be invoked from the EventBase loop (i.e., after the main POSIX signal handler has returned control to the EventBase thread).

Implements folly::AsyncSignalHandler.
