Errors in the upstream OVS Python IDL lib are not logged anywhere

[Terry Wilson]

The OVS IDL library, instead of passing exceptions, logs them via its Vlog wrapper around Python's logging module. Currently, we aren't getting any of these log messages. Since the library also doesn't pass exceptions to use, instead catching and logging them, this makes debugging difficult.

    Log OVS IDL library errors to neutron logs

    The OVS IDL library, instead of passing exceptions, logs them
    via its Vlog wrapper around Python's logging module. Currently,
    we aren't getting any of these log messages. This patch replaces
    the Vlog class log methods with the equivalent oslo_log methods.
