When config-download runs ceph-ansible it does so by calling Ansible from within Ansible. This change adds a new boolean, ceph_ansible_inherits_calling_ansible_environment (default: true), which passes all ANSIBLE_* environment variables to the nested Ansible execution. If a config-download user exported a variable, e.g. ANSIBLE_PRIVATE_KEY_FILE, then they might be surprised if they got to the Ceph installation and it failed because Ansible was unable to SSH into the target nodes because it didn't have that environment variable set. Rather than require the user to know about the nested execution and use the CephAnsibleEnvironmentVariables parameter, assume they want the same variables passed. Required TripleO defaults for ceph-ansible still take precedence over config-download environment variables; ANSIBLE_ROLES_PATH still refers to ceph-ansible roles, not config-download roles. CephAnsibleEnvironmentVariables takes precedence over both the calling Ansible environment variables and TripleO defaults for ceph-ansible. Change-Id: I428f6deb416b540dae552b5fc7a778cbc7505e8c |

Ansible Role to manage the exectution of ceph-ansible from within TripleO
Executes playbooks from ceph-ansible using parameters from TripleO.
After the working directory is created by the tripleo-ceph-work-dir role and the working directory has been populated with host_vars mapping node specific overrides by the tripleo-ceph-uuid role, and after the fetch directory is populated with context from previous ceph-ansible runs, by the tripleo-ceph-fetch-dir role, the playbooks from ceph-ansible may be executed.
This role creates the shell script ceph_ansible_command.sh within the ceph-ansible working directory and then executes the shell script. If the shell script's return is non-zero, the deployment fails and an error message from ansible is displayed.
After this role is used, the tasks from backup_and_clean.yml from the tripleo-ceph-work-dir role should be used to persist the ceph-ansible fetch directory and then remove it so that future runs of ceph-ansible by this role do not have permissions issues when the role is used by a different user.
Requirements
None
Role Variables
- ceph_ansible_playbooks_param: the list of ceph-ansible playbooks to be run; e.g. ['/usr/share/ceph-ansible/site-container.yml.sample']) is the default but any item in ceph-ansible/infrastructure-playbooks may be passed. If the list contains more than one item, each playbook is executed sequentially.
