def get_oneview_client(session_id=None, is_service_root=False):
    """Establishes a OneView connection to be used in the module

        Establishes a OV connection if one does not exists.
        If one exists, do a single OV access to check if its sill
        valid. If not tries to establish a new connection.
        Sets the connection on the ov_conn global var

        Args:
            session_id: The ID of a valid authenticated session, if the
            authentication_mode is session. Defaults to None.

            is_service_root: Informs if who is calling this function is the
            ServiceRoot blueprint. If true, even if authentication_mode is
            set to session it will use the information on the conf file to
            return a connection.  This is a workaround to allow ServiceRoot
            to retrieve the appliance UUID before user logs in.

        Returns:
            OneViewClient object

        Exceptions:
            HPOneViewException if can't connect or reconnect to OV
