Allow configurable default search index

[richadlr]

We have multiple kibana deployments, each connecting to same or different elasticsearch nodes. Thus, the index name is not always the default one ( [logstash-]YYYY.MM.DD ). We are forced to modify the dashboard template json files delivered with kibana (essentially logstash.json), plus a few customs to reflect the correct index ( index.pattern ). And have to repeat this everytime a new kibana release brings enhanced templates.

We would need a mechanism to specify the default search index that kibana would override before realizing the template and querying elasticsearch.

Setting could be in config.js, similar format as kibana_index ( kibana_index: "kibana-int", )
default_search_index: "logstash-env1-",

Logic would be:

if index_defined_in_dashboard != "logstash-"
index = index_defined_in_dashboard
else
index = default_search_index

It appears you've filed this in the wrong repository? See here: https://github.com/elasticsearch/kibana

Thanks, created elastic/kibana#1009 instead.
