The rabbitmq.config parameters heartbeat, handshake_timeout aren't specified

[Dmitry Dmitriev]

Detailed bug description:

 File /etc/rabbitmq/rabbitmq.config doesn't include parameters heartbeat, handshake_timeout.
 There is no ways to specify they values.

Steps to reproduce:

 1. Create new cluster with default parameters.
 2. Choose one node for controller role, one node for compute.
 3. Perform deployment.
 4. SSH to controller node.
 5. Cat /etc/rabbitmq/rabbitmq.config

Expected results:

 File rabbimq.config contains parameters heartbeat, handshake_timeout with specified values.

Actual result:

 There are no parameters heartbeat, handshake_timeout in rabbitmq.config file

Reproducibility:

  Every time during cloud deployment.

Workaround:

 No workaround.

Impact:

 Customer can't deploy clouds with important parameters. Deployment without specified parameters is not acceptable so this has to be addressed as soon as possible.

Description of the environment:

 Versions of components: {"release": "9.0", "auth_required": true, "api": "1", "openstack_version": "liberty-9.0", "feature_groups": []}
 Operation system: Ubuntu 14.04.4
 Reference architecture: HA and non-HA

This is actually not true.
All rabbit.* config options could be handled by 'rabbit_config_variables' in hiera.
For example:
  rabbit_config_variables:
    heartbeat: 60
    handshake_timeout: 10000

Note: "heartbeat" in seconds, "handshake_timeout" in milliseconds.

    Merge rabbitmq default config vars w/ custom ones

    Merge all sources of rabbitmq config variables in order to
    avoid the default settings loss in case when custom config
    options come from hiera.

Bug was reproduced on Fuel 9.0 ISO #142. Scenario:
1. Create new environment.
2. Add 1 controller and 1 compute.
3. Deploy changes.
4. SSH to controller node and cat /etc/rabbitmq/rabbitmq.config

heartbeat and handshake_timeout are missing from rabbitmq.config
