services: Update rabbitmq service

Update RabbitMQ default configuration to use localhost interface by
default and avoid listening on public interfaces.

Change the default configuration file to set inter-node communication
listener to localhost network interface (see also
https://www.rabbitmq.com/docs/networking#distribution). This requires
setting RabbitMQ node name to `rabbit@localhost`, so introduce
`node-name` RabbitMQ configuration field with such default value.

Path to the RabbitMQ environment configuration file was hardcoded.
Remove the hardcoding and allow to create such file with env-config-file
RabbitMQ configuration field.

Add new RabbitMQ service tests to check RabbitMQ broker startup and
status after the service is started.

* gnu/services/high-availability.scm (<rabbitmq-configuration>)
  [<node-name>, <env-config-file>]: New fields.
  (rabbitmq-shepherd-service): Use them.
  (%default-rabbitmq-config-file): Update.
* gnu/tests/high-availability.scm (run-rabbitmq-test): Add new tests.
* doc/gnu.texi (High Availability Services): Document new fields and
  provide information about local interfaces.
