Stopping ES during initial indexing leaves orphaned indexes

[Travis Tripp]

Need to determine if this is desired or not, but if you do not have any indexes created and start a bulk indexing job e.g.:

searchlight-manage index sync --force

Then in the middle of indexing stop elasticsearch, this will result in an error and leave orphaned index and aliases (-listener and -search).

Please note, that doing any recovery here is questionable (since ES is offline). I do wonder if there is anything we can do about this like tying into the orphaned-es-indexs [0] blueprint and publish information about starting an index job (e.g. into .searchlight index) at the beginning of a job and then doing something smart the next time it runs.
