Merge ~paulgear/telegraf-charm:master into telegraf-charm:master

[Paul Gear]

Proposed fix for lp:1659375; requires lp:1692178 to be fixed in order to be effective.

[Stuart Bishop (stub)]

Looks fine. As mentioned in the description, pointless to land until a corresponding charmhelpers fix has been released. A work around may be desirable if this is too annoying right now.

review: Approve

This is harmless to land now, and may be effective for any telegraf package which doesn't install in a disabled state.
