Make nova-api logs more useful

The current logs make it hard to identify what API command is actually
being called, especially for POST, where the action is in the body.

* Whenever there is body, log it (info level)
* Log what function the API command maps to (debug level)

Pull NovaWebSocketProxy class out of nova-novncproxy binary

To allow sharing of proxy code between nova-novncproxy and
nova-spicehtml5proxy, pull the NovaWebSocketProxy class
out of nova-novncproxy into a new nova/console/websocketproxy.py
file

Adds previously missing websockify dep to pip-requires.

Add a get_spice_console method to nova.virt.ComputeDriver API

To mirror the existing get_vnc_console method, add a new
get_spice_console method to nova.virt.ComputeDriver API.

No attempt is made to wire this up to the RPC API, since at
this time there is no equivalent of novnc or xvpvncproxy to
use with SPICE.

Move compute node operations to conductor

This adds the following operations to conductor:

  compute_node_create()
  compute_node_update()

It also makes resource_tracker use them instead of making direct
calls to the database.

Further, it introduces a convert_datetimes() helper to the db api,
which can be used internally to convert ISO time strings back to
datetimes, so that we're getting them over the RPC wire. This
should be used in other places in the future to fix similar
situations and avoid one-off conversions in random places.

This removes the last direct database call from resource tracker,
and thus the db import.

Fix fallback when Quantum doesn't provide a 'vif_type'

    Make Quantum plugin fill in the 'bridge' name

We changed libvirt VIF driver to pull 'bridge' out of the
VIF model. This only worked for new Quantum drivers that
provide the 'vif_type' portbinding metadata though. This
patch effectively reverts part of that patch, so we have
a combination of the new & old method for determining
bridge names. The libvirt VIF driver will look at the
network['bridge'] field first, and if missing will fallback
to its previous logic which hardcoded bridge names.

enforce server_id can only be uuid or int

the get() function takes an arbitrary id coming from the rest url
for the server. In our current code it checks if this is a proper uuid
and sends it down the uuid path, everything else gets dispatched to
the version that selects by integer id. This means that arbitrary
garbage fuzzed server ids will get sent down the int path, all the way
to the database.

In postgresql, where the db is strongly typed, this causes a type error.
This error was found by tempest nightly runs where we send some 35 and 37
character strings in.

This patch creates and equivalent is_int_like function. If the server_id
is neither uuid_like nor int_like, we throw the InstanceNotFound exception
early. This also saves us a trip to the database in these cases.

Make the is_int_like a little more robust, and don't succeed on floats

Once more with feeling, to let us actually use is_int_like on ints, not
just strings.

libvirt: Optimize test_connection and capabilities

The getCapabilities call can be very slow so it is not a good choice
for testing the libvirt connection. This patch switches to
getLibVersion and also caches the result of getCapabilities so it
doesn't need to be requested every time. Note that this means that
nova-compute will need to be restarted if the capaabilities of the
host changes. This is an acceptable risk because capabilities
changes should be very rare and nova-compute should be restarted
if libvirt is restarted or reinstalled.

This simple change lowers boot time in my devstack install from
22 seconds down to 8 seconds!

Better instance fault message when rescheduling.

The old code would use exc_info[0] which is the type of exception, not
the exception itself. This would result in the `message` attribute
always being 'type' and the first-line of details being useless.

The solution is to pass the actual exception object so that `message`
becomes the class-name and the first-line of details becomes the `repr`
of the exception object.
