KVM: add an instance uid file concept

If this file exists, for an instance, we release the uid contained
inside back to the uid pool, at instance shutdown.

KVM: move post-shutdown cleanup operations

Currently putting the cleanup just after the actual shutdown ensures
that it never gets called, due to how the retry/shutdown cycle works.
So we move those cleanups to their new dedicated place.

Add CleanupInstance hypervisor call

Currently some hypervisors (namely kvm) need to do some cleanup after
making sure an instance is stopped. With the moving of the retry cycle
in backend those cleanups were never done. In order to solve this we add
a new optional hypervisor function, CleanupInstance, which gets called...

Move the runas user at execution time

Everything still works the same way, but the user is calculated each
time we start kvm, rather than stored in the config file. This makes it
easier to implement the "pool" security model.

Extend the hypervisor API with name-only shutdown

Currently the ShutdownInstance method of the hypervisors takes a full
instance object. However, when doing instance shutdowns from the node
only, we don't have a full object, just the name.

To handle this use case, we add a new ‘name’ argument to the method,...

KVM: Check instances for actual liveness

Currently if we find a live process with the pid we saved we assume kvm
is alive. What could happen, though, is that the pidfile has been
reused.

In order to avoid that we change the check to make sure, everywhere,...

KVM: remove unused variable

We don't need the pwentry when checking if a username exists, just to be
sure the KeyError is not returned. Remove the variable, and thus shut up
lint.
