kvm console: use socat raw mode with escape

If this is enabled at configure time, we pass in different parameters to
the socat console, making it a lot more manageable.

KVM netscript: add static routes, with no suffix

The /32 suffix is useless, since the kernel already assumes single-host,
if no suffix is specified. Moreover we prefer these routes to be
"static" so that routing daemons, if present, won't mess with them....

KVMHypervisor: implement instance policy routing

Until now we relied on traffic from instances being policy routed via a
rule based on the instance network. With this change we can enforce it
on the instance interfaces. Since the ip rules survive interface...

KVMHypervisor: configure v6 parameters on nic

In routing mode we are tweaking a few parameters on the interface. With
this patch we'll tweak both the v4 and v6 ones.

Xen: Ignore the retry argument in stop instance

Commit 4ad4511 changed the KVM hypervisor to send multiple shutdown
requests to the monitor, but it didn't change this for the Xen
hypervisor. We simply remove the return on retry model, since we do want
to send multiple shutdown signals for both Xen and KVM (even if the...

ChrootManager: clean StopInstance

Currently it has lots for duplicated code, and internal retries.
Clean it up with the following assumptions:

We'll probably be called more than once.
It is ok to fail to stop, unless we're called with force=True.
If we're called only once, and with force=True it's ok not to run the...

KVMHypervisor: use the StopInstance retry feature

Since we know StopInstance is going to be called more than once (at
least twice, once with force and once without, but normally quite a lot
more) we don't need our own sleep/loop, and we can just send one monitor...

Hypervisors: Add retry= to StopInstance

Currently some hypervisors need the stop operations to be retried more
than once, while other ones only do it in one pass. With this change
we'll handle retries outside the hypervisor code, but telling whether
this is the first try or not....
