Support configuration of resource providers with config files

Code Issues Proposed changes

Resource providers can be configured using the API or CLI, or they
can also be configured on a per-compute node basis using config
files stored in /etc/nova/provider_config.
This patch adds support for a user defined list of provider config
files to be created on the compute nodes. This can be specified in
user_variables or perhaps more usefully in group_vars/host_vars.
A typical use case would be describing the resources made available
as a result of GPU or other hardware installed in a compute node.

Support is added to the os_nova ansible role to deploy resource provider

config files to nova compute nodes. This allows automatic configuraion

of resource providers without having to use the openstack API or

command line.
