[Fixes #1562] Add example index pattern to Settings > Indices

[kkirsche]

Fixes Issue #1562 by providing information to the user using the kbn-info directive. Verbage used is based on Logstash's elasticsearch output (http://logstash.net/docs/1.4.2/outputs/elasticsearch#index) documentation.

I think I'd rather see this as text under the label, that changes depending on if the user has Use event times to create index names enabled. Putting complex(ish) examples in the tooltip makes it hard to copy and paste the example.

That makes sense. Let me take a look at doing that with a help-block underneath. Thank you for the feedback.

Made that adjustment @rashidkpc — let me know what your thoughts are.

Would it make sense to also move that "docs" link down to that line of text as well? And maybe give the link a little more context? It links to the moment date parser, which always seemed kind of odd to me.

After reading through #1562 - perhaps that index selection needs more comprehensive documentation?

[kkirsche]

@w33ble — I think moving the "docs" link to the ng-if for when both "Index contains time-based events" and "Use event times to create index names" are checked as it seems to make the most sense in that context specifically.

When you say more comprehensive documentation do you mean within the UI of that page or somewhere else?

[kkirsche]

@w33ble — I see what you mean. What are your thoughts of only showing it contextually when "Index contains time-based events" and "Use event times to create index names" are checked as seen below. I think this better describes what the documentation is for and when it is truly helpful.

When you mention more comprehensive documentation do you mean on the UI page or elsewhere?

Let me know, looking forward to making any changes necessary.

LGTM

In general, I think we could definitely use more information about how to specify the index pattern, but I really like how this turned out with what we have there. Nicely done.
