'port' should be optional arg to VerifiedHTTPSConnection

[Stuart McLaren]

VerifiedHTTPSConnection inherits from httplib.HTTPSConnection.

HTTPSConnection doesn't require that a port is supplied:

    class HTTPSConnection(HTTPConnection):
        "This class allows communication via SSL."

        default_port = HTTPS_PORT

        def __init__(self, host, port=None, key_file=None, cert_file=None,
                     strict=None, timeout=socket._GLOBAL_DEFAULT_TIMEOUT,
                     source_address=None):

if port isn't present it attempts to parse the port value from host (eg localhost:8443)
or else defaults to 443.

We should match this, and have port be an optional parameter.

    Change https port to be an optional parameter

    VerifiedHTTPSConnection inherits from HTTPSConnection so 'port' should be
    an optional argument. If not present it will be set by HTTPSConnection
    in the usual way: by parsing the host string (eg 'localhost:8443')
    or setting to the default of '443'.

    Addresses bug 1102944.
