Can you provide a the Python program you requested given the following:
Complete the below
def _loopbackTLSConnection(serverOpts, clientOpts):

    ''''Common implementation code for both L{loopbackTLSConnection} and
    L{loopbackTLSConnectionInMemory}. Creates a loopback TLS connection
    using the provided server and client context factories.
    @param serverOpts: An OpenSSL context factory for the server.
    @type serverOpts: C{OpenSSLCertificateOptions}, or any class with an
    equivalent API.
    @param clientOpts: An OpenSSL context factory for the client.
    @type clientOpts: C{OpenSSLCertificateOptions}, or any class with an
    equivalent API.
    @return: 3-tuple of server-protocol, client-protocol, and L{IOPump}
    @rtype: L{tuple}'
