Make scheduler disk_filter take swap into account

The disk_filter, which makes sure a node has enough disk space for an
instance doesn't take the swap partition into account, but swap takes up
disk space so it should.

Remove multipath mapping device descriptor

When detaching a volume from a instance, we need to remove
multipath mapping device descriptor if there are other volumes
mapping to the host instead of do nothing, for some cinder drivers
can not terminate connection for multipath tool sending IOs to
storage array periodically.

Stored metrics into compute_nodes as a json dictionary

The compute manager uses plugins to get the metrics information of each node.
And then sends and stores in DB for the scheduler to read and do scheduling.

The patch reuses table compute_nodes and adds a new TEXT column to store the
metric data as a json dictionary.

This is part of the blueprint utilization-aware-scheduling and the
blueprint generic-host-state-for-scheduler.

Fix migration 185 to work with old fkey names

Migration 133_folsom.py accidentally changed the name of the FK
constraint on instance_info_caches from instance_info_caches_ibfk_1
to instance_info_caches_instance_uuid_fkey and on virtual_interfaces
from virtual_interfaces_ibfk_1 to
virtual_interfaces_instance_uuid_fkey meaning databases who have
upgraded from before folsom have the old fkey.

This patch adds a check for those with the old fkey name to make sure
it is dropped before changing unique constraints (as is required by
MySQL). It also fixes the fkey name to be as defined in 133 if it
wasn't before (which will persist on downgrade being consistent with
those who have come in after folsom).

Fix interface-attach removes existing interfaces from db

The following commit 394c693e359ed4f19cc2f7d975b1f9ee5500b7f6 changed
allocate_port_for_instance() to only return the ports that were created
rather than all of the ports on the instance which broke the attach-interface
code.

This patch fixes this issue by remove the sync decorators from:
allocate_for_instance, allocate_port_for_instance, and
deallocate_port_for_instance to just _build_instance_nw_info which
is called in all these cases instead.

The method assertEquals has been deprecated since python 2.7.

Also in Python 3, a deprecated warning is raised when using assertEquals
therefore we should use assertEqual instead.
