Ability to set default time span

[mrfelton]

We can set the default dashboard by setting DEFAULT_APP_ID.

Kibana defaults to showing only the last 15 minutes of data, which isn't great for many types of dashboards. This can be altered by adjusting timeDefaults in kibama.yml. See http://stackoverflow.com/questions/29654254/how-to-change-kibana-4s-default-time-filter for example

It would be useful to be able to set this through the docker container much like we can for the default app id.

Oh, sorry, accidentally closed that issue. We can make the default app id editable if you like. oh, that's already done.

To edit that default time filter from outside is a bit of a hack. But I'm accepting a pull request for that.
But it may be complicated to maintain that and therefore too much hassle to implement that.
I don't know whether there's still some demand for this dockerfile.
