rebuild does not allow changing SSH keys

[Johannes Erdfelt]

The compute API allows optionally setting adminPass and key_name for server creates, but only allows optionally setting adminPass for server rebuilds.

This means that the key_data for an instance is effectively immutable. The key pair is retrieved during a server create and sets key_data, but appears it can never be changed.

This wishlist bug has been open a year without any activity. I'm going to move it to "Opinion / Wishlist", which is an easily-obtainable queue of older requests that have come on.

In case you want to work on that, consider writing a blueprints [1] and spec [2]. I'll recommend to read [3] if not yet done. The effort to implement the requested feature is then driven only by the blueprint (and spec).
