Mathieu Bultel d26d5c680d Dump all deployment role_data files to a config dir ...

Add new overcloud cli command in order to dump
all the configs from the overcloud contains in role_data.
All different type of configs are dump in a separate file
per role ex:
ls config/tmpD2nDOd-config/
config_settings-Compute.yaml
global_config_settings-Compute.yaml
logging_sources-Compute.yaml
monitoring_subscriptions-Compute.yaml
service_config_settings-Compute.yaml
service_metadata_settings-Compute.yaml
service_names-Compute.yaml
step_config-Compute.yaml
upgrade_batch_tasks-Compute.yaml
upgrade_tasks-Compute.yaml

The upgrade_tasks is in yaml format and can be directly
call with ansible-playbook command, example:

$ cat config/tmpD2nDOd-config/upgrade_tasks-Compute.yaml
- hosts: Compute
  name: Compute playbook
  tasks:
  - name: Stop snmp service
    service: name=snmpd state=stopped
    tags: step1
  - name: Stop nova-compute service
    service: name=openstack-nova-compute state=stopped
    tags: step1

This patch to allow operators to run manually
the upgrade tasks via ansible on the Undercloud.
