Fix to configure RABBIT_CAPABILITIES

This PS fixes the rabbitmq exporter configurations.

Now, RABBIT_CAPABILITIES env values can not be set because of dummy
values.

After fix values, it needs to upgrade exporter image version because
of string parsing problem in the exporter.

Additional, bert option is added.
