    Copy undercloud.conf file during mistral-executor start up.

    As we are changing the ownership of the whole /var/lib/mistral directory in a
    recursive way, we can't be mapping /var/lib/mistral/undercloud.conf as read-only,
    otherwise we will get a OSError: [Errno 30] Read-only file system: '/var/lib/mistral/undercloud.conf'.

    Instead, we will be mapping the undercloud.conf file into /var/lib/ directory
    inside the container and then copy it from /var/lib into /var/lib/mistral
    directory on start up, this way we will get rid of ownership permission issues.
