Add default index pattern for Kibana per user or role

[elasticmachine]

Original comment by @gmoskovicz:

It would be great to add a default index pattern per user or role. I am opening this feature request in the x-plugins repo because this looks more like an enhanced feature for multitasking when Shield (and Shield plugin) is enabled and installed.

Today, if you don't have a single default index pattern accessible from all the roles in shield, Kibana will fail because it will not find the default index pattern configured in the config document. In the future, it would be great to define a per user or role pattern, or a fallback into other "visible" patterns when someone has no access to the default pattern.

I believe it is improved with spaces but the problem still is not solved. Perhaps instead of the default index pattern, we can show the last index pattern used, it will likely improve many of these use cases.
@timroes is it possible to cache in the browser the last index pattern (similar to recent objects used)?
