SwiftSignalHandle resource ID can be too long for DB column

[Jason Dunsmore]

Similarly to the following RandomString bug: https://bugs.launchpad.net/heat/+bug/1392359, the SwiftSignalHandle URL can be too long for the database column, resulting in an exception:

2014-12-02 23:02:19.789 5472 ERROR oslo.db.sqlalchemy.exc_filters [-]
DBAPIError exception wrapped from (DataError) (1406, "Data too long

    Use physical_resource_name to generate the resource ID

    The SwiftSignalHandle URL can be too long for the database column,
    resulting in an unhandled exception and failed stack.

    Use the SwiftSignalHandle's physical_resource_name() method to generate
    the resource ID and use FnGetRefId to fetch the handle URL instead.
