Remove baremetal-compute-pxe.filters

The baremetal PXE driver doesn't seem to run dnsmasq at all, so remove
the rootwrap filter which allows it to do so. This was introduced by
commit a2f260f.

PXE driver should not accept empty kernel UUID.

Baremetal PXE driver was aborting only if the kernel and ramdisk
specified in image metadata were None, but not if they were another
non-true value, such as "". Now, exception is raised if they are any
non-true value.

Fix bug 1100589.

Remove obsolete baremetal override of MAC addresses.

Now that the hypervisor driver can specify what MAC addresses it
needs, overriding the MAC address during bare metal instance
provisioning is no longer appropriate.

Remove restoring soft deleted entries part 1

There is no need to reuse deleted entries, because they will be archived after
db-archiving implementation. And restoring soft deleted entries produce some

Directly copy a file URL from glance.

That patch allows nova to use shutil to copy a file directly from the
glance store.  For this to work glance needs to enable direct_url
descriptions in the image metadata.  This is done by setting
show_image_direct_url to True in glance-api.conf.  The path used to back
glance also must match the path used to back nova instance storage.  This
should be a large performance increase for the cases where both glance
and nova instance storage are backed by a shared file system like gluster
or ceph.

A new option has been added to nova: allowed_direct_url_schemes
This option is set to a list of schemes that can be directly accessed.
For this first simple patch only file:// is valid, and the
implementation is simple and inline.  In the future it would be better
to make this into propagation modules which are dynamically loaded
according to the scheme.

Refactor EC2 keypairs exception

According to the following document:

http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/api-error-codes.html

The EC2 API sends specific error codes when keypair listing or
keypair generation fails, specifically the error codes are

InvalidKeyPair.Duplicate - duplicate keypair
InvalidKeyPair.Format - keypair format invalid
InvalidKeyPair.NotFound - keypair not found
ResourceLimitExceeded - keypair quota exceeded

Refactored create_key_pair and describe_key_pair so that
it throws the correct EC2 error codes according to the
public EC2 API specs.

Also removed some duplicate exceptions as well.
