Remove default request looking for logstash-* on pattern creation page

[mostolog]

Hi

When browsing to /app/kibana#/settings/indices, on page load, Kibana tries to find logstash-* index-pattern, making a request to _/elasticsearch/logstash-/mapping/field/ which results on 404.

As we are monitoring requests, this is adding some garbage that - IMHO- could be avoided.

Wouldn't be greater if that request its only made when Kibana doesn't have any indexes?

I'd actually like to remove the default logstash-* value completely.

I'm ++ on @Bargs suggestion on removing the default value. But I think that users will benefit from having a default value. When I first installed Kibana (first time ever) it was nice to have something rather than nothing... even though it didn't help me a ton.

I'd like to give my personal preference as an idea. I have developed a habit of typing * because it's what I typed when I didn't have much understanding of Kibana in general. I think that it's a generally well-known concept that * will fetch any index pattern and it gives users more context on what Configuring an index pattern page is about since we don't offer auto complete or anything like that. At least this way, they will see something, and be able to create an index that will allow them to move forward. I realize this might have its own downsides such as we might not want to encourage users to create this pattern as they might have some enormous amount of data.
