Merge lp:~michael.nelson/charms/trusty/kibana/trunk into lp:~canonical-is-sa/charms/trusty/kibana/trunk

[Michael Nelson]

Merge upstream (which now has web-relation-joined http relation).
Fixed conflicts.
Fixed charm proof errors.

This branch just re-merges the upstream lp:charms/trusty/kibana and resolves the conflicts (main one being that upstream still uses 'web' rather than 'website', even though it's changed the type to 'http').

Once this is merged, we should be able to ask for this MP to be merged upstream:

https://code.launchpad.net/~canonical-is-sa/charms/trusty/kibana/trunk/+merge/260026

so that the exec.d support and elasticsearch url support gets added upstream.

I'm just testing this now with a local deploy.

This looks good.
