Move more hypervisor strings into constants

This patch adds constants for the mouse and boot order strings; while
there are still some issues remaining, we're trying to cleanup hardcoded
strings from the hypervisors.

Since the formatting of frozensets is currently wrong, we also add an...

Move HVM's device_model to a hypervisor parameter

This moves yet another hardcoded value to a hypervisor parameter. I
removed the 64/32 difference as it doesn't seem valid to me - it's more
of a local site config rather than arch config.

Fix xen-hvm and KERNEL_ARGS

xen-hvm doesn't have KERNEL_ARGS, and I just changed blindly all old
extra_args to HV_KERNEL_ARGS. This makes xen-hvm work again.

Remove the extra_args parameter in instance start

This patch removes the extra_args parameter and instead switches the
instance to the HV_KERNEL_ARGS hypervisor option.

This is a big change, but it's a needed cleanup, this extra parameter on
all RPC calls is not generic and we also need to have a persistent value...

Simplify a little the hypervisor routines

Instead of “instance.hvparams”, we use a shorter “hvp” name to make readability

Rename the device type constants

These are not HVM specific, so have been given an HT generic name.

s/HT_HVM_VNC_BASE_PORT/VNC_BASE_PORT/g

The VNC base port has nothing to do with HVM itself, and is general to
VNC itself, so we're removing the HT_HVM prefix to the constant.
