Service nova-network starts automatically when package gets installed on Ubuntu linux, this behaviour breaks OSTF check: Check that required services are running

[Igor Zinovik]

Environment:
 Ubuntu as target OS
 3 controller
 vCenter enabled

Problem description:
During deploy nova-network service start automatically after its package was installed. When nova-network starts it creates a record in database with 'host' parameter. This makes OSTF tests to fail, becase nova database contains record of services
that were started with wrong host parameter.

This bug is related to https://bugs.launchpad.net/fuel/+bug/1426040

Steps to reproduce:
1. Create cluster with Ubuntu
2. Deploy 3 controller
3. Run OSTF or execute nova service-list

Expected result:
There are no services in 'down' state.

Actual result:
Several nova-network services appear with state 'down', because they are started on

Impact:
This behaviour breaks OSTF tests.

    Do not start nova-network service on Ubuntu after package installation

    - apt-get on Ubuntu automatically run nova-network service after package
      installation, during this first run nova-network cannot be started
      with customized configuration file it leads to this: it records in
      database with nodes host name (e.g. 'node-2') and even if we start it
      with customized configuration file old record will be in database with
      state 'down'. All this leads to failed OSTF test: "Check that
      required services are running".
