Bug Description

[Impact]
Unresponsive machines cannot be removed/destroyed, consuming resourcs.

[Test Case]
This of course requires a unresponsive machine; however this can be simulated by destroying a machine that is still installing.

juju destroy-machine <machineid> # will fail

juju destroy-machine --force <machineid> # will succeed

[Regression potential]
Part of the upstream tested 1.16.6 point release.

[Original bug report]
Unresponsive machine agents may require that we forcibly set the machine to Dead to allow the provisioning agent to release its instance.

I consider this low priority until we have the unit story sorted out cleanly.

...but still, actually, high priority; just that it should be done after the unit is, because a replacement for a zombie machine generally cannot act usefully without replacements for its assigned zombie units in play.

This is something we'd like to consider backporting to the 1.16 series. We may decide not to, but we don't want to forget about it.

so for folks on 1.16.3 i've had put together a script that does the direct db deletion. it should only be considered after db introspection as its specifically around the scenario of a machine with no units, stuck in dying. it comes with no warranty, if you need to use it please ping me on irc before hand.

Script to dump db for for foresenic analysis, used to verify db structure before use of machine removal script.

The changes for this got bumped off to the side in my lp:~jameinel/juju-core/preparation-for-1.16.5
So I'm retargetting this for 1.16.5.

The changes were landed back into the 1.16 series.
