Use new compute.instances.update API

Enabling support for this seems quite difficult.
Not all properties can be updated together. Some properties require RESTART and some require REFRESH.

Note: properties that require REFRESH cannot be updated during RESTART.

edit: RESET -> RESTART

[danawillow]

By RESET you mean RESTART, right? My impression from reading that page is that you specify the most disruptive allowed action, and then the API itself decides what to do, which would mean that if you said RESTART was allowed and you passed in a mix of REFRESH and RESTART properties, that it would restart the instance and update all of them.

I think your interpretation is the correct one after re-reading the documentation.
