_ExecuteKVMRuntime: fix hv parameter fun
When executing the kvm runtime we were currently accessing a mix of the
parameters as configured currently on the instance and the ones it was
started with. We were doing it without a precise criteria, but quite by
chance we got it almost right. The only remaining issue was that when
ganeti was upgraded and some parameters were added, trying to access
them from the "old" ones caused a keyerror, since they weren't present
back when the instance was started.
To fix this:
- We fill the startup-time dict with any new parameter
- We provide a clear guideline on which version of the parameters to
access, and about the fact that new parameters must have an
instance-migration backwards compatible default
