add config toggle to disable any package updates on cloud-init

[maigl]

This adds a config toggle to disable any package install or updates during boot / cloud-init.

This PR belongs to cloudbase/garm#84

Remarks:

I'm no really happy to duplicate this entire function just to add this if.

Yeah, you are right. In the future, I think we should make this part a bit more granular to allow easy customization. For now, I think the easiest and quickest thing to do is add an extra param to GetCloudConfig() function in garm itself that disables updates. This way we don't have to copy it just for this.

Feel free to create a PR in garm that adds the flag. We can vendor it here and make use of it.

.. or maybe we could add a new field UserDataOptions to the BootstrapInstance struct? This could be the first step towards more customization..
