Add "canasta elasticsearch index" command

[yaronkoren]

It would be good to have a "canasta elasticsearch index" command. This would, of course, only be usable if Elasticsearch and the CirrusSearch extension are installed. I'm told the set of actual commands it should call is:

maintenance/UpdateSearchIndexConfig.php maintenance/ForceSearchIndex.php --skipLinks --indexOnSkip maintenance/ForceSearchIndex.php --skipParse

...all within the CirrusSearch/ directory. I don't know if that's correct, but it seems like a good starting point.

Potentially there could be other "elasticsearch" sub-commands that it would be useful to have in the future.

That is correct. Maybe add a --force flag (or whatever it's called) to UpdateSearchIndexConfig.php too.

Here are a few commands I use to check the health of ES; not sure if it's helpful, maybe could be incorporated into the new command:

curl -X GET "localhost:9200/_count?pretty" -H 'Content-Type: application/json' -d'
{
    "query": {
        "match_all": {}
    }
}
'

or

curl -X GET "localhost:9200/_cluster/health?pretty"

Gives you some basic info on the cluster/shards and a green/yellow/red health status.

For reference, the index command should print out the script results. I think this is your intent: i.e.:

Couldn't find a --force flag. Instead found --startOver: Blow away the identified index and rebuild it with no data. Is this the right one?

[jeffw16]

Yes, it's --startOver

@jeffw16 I'm interested in working on this. Could you please assign it to me?
