The playbook re-execution script should be moved to the users home folder

[Kevin Carter]

When executing tripleoclient commands the client provides the ability to re-execute a given ansible command via the `ansible-playbook-command.sh` script. This script original was owned and created by mistral, however, with the removal of mistral there is no expectation that the user (generally stack) has 100% to all files and folders owned by mistral and its respective container. We should move the write path for the script `ansible-playbook-command.sh` to the users designated output directory so that we're not making the assumption the client is able to write into a container path.
