This patch adds the workflow definition and actions
to perform an Undercloud backup.
Workflow can be executed as:
mistral execution-create tripleo.undercloud_backup.v1.launch
Actions can be invoked as:
mistral run-action tripleo.undercloud.get_free_space
mistral run-action tripleo.undercloud.create_backup_dir
mistral run-action tripleo.undercloud.create_database_backup \
'{"path": "/tmp", "dbpassword": "", "dbuser":"root"}'
mistral run-action tripleo.undercloud.create_file_system_backup \
'{ "path": "/tmp/undercloud-backup-dCxQSn", "sources_path": "/home/stack/"}'
mistral run-action tripleo.undercloud.upload_backup_to_swift
mistral run-action tripleo.undercloud.remove_temp_dir
