Log port on failed bind?

[jvanasco]

It would be useful, at least to me, if waitress had some logging info here:

waitress/src/waitress/wasyncore.py

Lines 372 to 374 in ed0149b

	def bind(self, addr):
	self.addr = addr
	return self.socket.bind(addr)

A failed bind looks like this:

  File "/home/jvanasco/peter_sslers-virtualenv-3.10/lib/python3.10/site-packages/waitress/server.py", line 243, in __init__
    self.bind_server_socket()
  File "/home/jvanasco/peter_sslers-virtualenv-3.10/lib/python3.10/site-packages/waitress/server.py", line 364, in bind_server_socket
    self.bind(sockaddr)
  File "/home/jvanasco/peter_sslers-virtualenv-3.10/lib/python3.10/site-packages/waitress/wasyncore.py", line 374, in bind
    return self.socket.bind(addr)
OSError: [Errno 98] Address already in use

When dealing with deployments and testing, the port is likely buried in a config file. It would just be nice to have more info on that error flash in my face.

perhaps one of:

    def bind(self, addr):
        self.logger.log(logging.DEBUG, "Attempting to bind to %s" % addr)
        self.addr = addr
        return self.socket.bind(addr)
        
    def bind(self, addr):
        self.addr = addr
        try:
            return self.socket.bind(addr)
        except:
            self.logger.log(logging.CRITICAL, "Failed bind to %s" % addr)
            raise
