heat.cloudinit config file disables critical modules

[Clint Byrum]

The cloud_config_modules: section of heat.cloudinit seems to want to be enabling more than the default. But this is actually not the case. In recent cloud-init code, the new list entirely replaces the old one.

This makes it impossible to use the ephemeral disk partition, which is mounted by the 'mounts' module.

We should consider dropping the modules list entirely.

This is blocking the TripleO work to use the ephemeral disk for state.

    Do not override cloud-init cloud_config_modules

    In the past it may have been necessary to do this but it causes problems
    for users of advanced features. We should be able to operate with the
    default OS configuration of cloud-init.
