states: Break on error, retry states up to 5 times

While applying scenario states, break on error, and retry failed
state up to 5 times. Apply the same behavior for `salt.sh`.

Add new deploy parameter, '-D', backed up by 'CI_DEBUG' env var,
which gates deploy sh scripts logging (set -x).
Also extend '-f' deploy parameter, allowing it to be specified
more than once; the first occurence will skip infra VM creation,
but still sync reclass & other config from local repo, while a
second occurence will also disable config sync.

To prevent glusterfs client state from failing due to non-existent
nova user/group, move it after nova:compute's nova state is applied.
