With current version of rabbitmq-exporter,
unable to retrieve data sometimes,
failing with rabbitmq timeout issues.
Rabbitmq timeout threshold is set as 10 sec
and is not configurable with current version.

Updating the rabbitmq-exporter version to
kbudde/rabbitmq-exporter:v1.0.0-RC7.1
(Default "RABBITMQ_TIMEOUT" set as 30 sec)
to solve rabbitmq timeout issues.
