Completes the power_state mapping from compute driver and manager

Fixes bug 1166906

Added extra states to constants module together with test
cases checking every state map.

Also added some debug statements under blockdev and operator
to be able to spot obvious issues with images at deploy time.

Allow listing fixed_ips for a given compute host.

nova.db.fixed_ip_get_all_by_instance_host was removed in commit
bb867ce3948ddc23cf928ca3dda100a1a977896a, but was still used in
nova-manage. This patch works around the removal of the foreign
key that led to this method being removed.

Resolves bug 1163660.

Import and convert to oslo loopingcall.

Import the oslo looping call implementation (which is a copy of
nova's), delete nova's local copy, convert all users to the new
location.

It should be noted that the oslo implementation of
FixedIntervalLoopingCall measures time from the start of the
periodic task, not the end, so periodic tasks will run with a
constant frequency instead of the frequency changing depending on
how long the periodic task takes to run.

Cleanup and test volume usage on volume detach

* Refactor _poll_volume_usage to be more readable

* Test that detaching a volume updates the totals on the volume usage
  cache correctly. This works but adding test to make sure that it always
  works.

hypervisor tests more accurate db

The hypervisor tests don't accurately model the db because the
sqlalchemy DB API requires admin for the compute_node_get_all
function.

This change makes it so that the fake compute_node_get_all
function in the hypervisor test module requires admin just like the
sqlalchemy DB function.

Translate cinder NotFound exception

When we attempt to get information about a snapshot
which doesn't exist we get a cinder NotFound exception.
However, this is not caught and causes a stacktrace in the logs.
This occurs on every tempest run in the test
EC2VolumesTest.test_create_volume_from_snapshot.

The fix is to translate the exception to SnapshotNotFound
which is handled correctly further up the call chain.

Map internal S3 image state to EC2 API values

Fixes the EC2 API so it maps internal S3 image state values to
ones defined by the EC2 API rather than returning the internally

Translate NoMoreFloatingIps exception

When the pool of floating ips is exhausted the NoMoreFloatingIps exception
is raised but not handled properly in the floating ips extension resulting
in the exception propagating further up and causing a stack trace to be logged.

This change translates the exception explicitly into a HTTPNotFound, preserving the current
REST API behaviour. It fixes a bug where the pool name was not correctly inserted into
the message returned if allocation from a specific pool was requested.

which is unnecessary, given that correct calculations can be made

Fix ec2 CreateVolumes/DescribeVolumes status

In admin context CreateVolumes/DescribeVolumes returns
extraneous information such as project_id, host, instance
data etc. This results in output which is not compatible
with the ec2 API. This change removes the addition
of the extra information.

This only partially fixes bug #1074901 as mapping the internal
volume states to ones specified by the ec2 api results in the devstack
euca.sh exercises to fail. But that can't be fixed until the fix
in this patch is through as the extraneous information returned by DescribeVolumes
causes euca-describe-volumes to not to show the attachment state for
a volume which is needed by the euca exercises.

Adds tests to xenapi.vm_utils's 'lookup' method

Change-Id: I140f091b50c3e4076d3f4812cae00e37f120a277
Allows xenapi 'lookup' to look for rescue mode VMs

When you lookup a VM by name, you can specify if you want it to check if
it has a rescue mode instance running.

If it finds the rescue mode instance, it'll return that one instead
of the original name.

This is useful for operations that should work on the rescue mode vm if
it's there, or the normal one, if it's not.
