deallocate_fixed_ip attempts to update deleted ip

Fixes bug 1017633. When deleting a vm, the nova
network manager looks to deallocate wrong fixed
ip when context has read_deleted set to 'yes',
in case when a network had been deleted and re-
created , it attempts to update already deleted
fixed_ips and therefore looks to teardown from
wrong network_id as well.

Flesh out the README file with a little more useful information

The current README file contents are amuzing, but could contain
more useful information for downstream users / developers. This
is an attempt to fill out the README file with further content.

Add check for no domains in libvirt driver.

A check is needed to see if there are any domains before calling
the listDomainsID() method. This check is needed to add support
for OpenVZ which will throw an exception from this method if there
are no domains. The 'virsh' source code does this check, too.

This change circumvents this libvirt bug:

Refactoring code to kernel Dom0 plugin.

The kernel and ramdisk VDI manipulation code really has nothing to do
with Glance so it doesn't make a lot of sense for it to exist in the
Glance Dom0 plugin.

This patch refactors the code out to its own plugin and then applies a
few misc cleanups.

Get hypervisor uptime.

Adds a call to retrieve the current uptime on a specific hypervisor.
This version of the patch only adds the XenAPI variant; other virt
drivers will raise a NotImplementedError until they implement the
get_host_uptime() method.

Create instance in DB before block device mapping

Fixes lp 1019334

A recently added foreign key constraint on the the block_device_mapping
table causes boot-from-volume to fail, as the bdm is populated before the
instance DB entry is created.

This fix simply transposes the ordering to avoid breaking the constraint.

Run hacking tests as part of the gate.

Nova has additional pep8 "plugins" that they expect to run as part of the
gate. This patch will run tools/hacking.py instead of pep8 directly. Also,
it fixes the hacking violaions in contrib, plugins and smoketests.

Fixes bug 1010136
