Adjust audit logs to avoid negative disk info

When requesting more disk than is available, the audit
logs will report negative values. This may confuse the
user or make him/her think the tracking is innaccurate.

This patch seeks to remove any confusion. It is in the
same vein as https://review.openstack.org/#/c/93261/
which addresses the same issue in regards to cpu and
memory audit logs.

Xen: Attempt to find and cleanup orphaned SR during delete

Before some patches merged to better handle failures to boot an instance
from a volume it was possible to have an attached volume with an SR and
plugged PBD but no VM.  And the destroy method in xenapi short circuits
if no VM is present because everything is looked up from there in order
to be cleaned up.

This adds a check to see if a volume is supposed to be attached during
destroy if no VM is present and attempts to look it up via the SR uuid
and clean it up.

I would like to say that this patch is unnecessary, as it's sort of
hackish, but it's possible that some deployments have instances in this
state and this will allow them to cleanup without manually running
commands on the hypervisor.

libvirt: convert mox to mock in test_utils

Commit 73066aff1b4c80f09a1340ab5d70b3b4f2983c0b created a new
file called test_utils. This was a good place to change
all mox usage to mock.

Fix unsafe SSL connection on TrustedFilter

TrustedFilter was using httplib which doesn't check for CAs.
Here the change is using Requests and verifies local CAs by default (or another
one if provided)

move integrated api client to requests library

The integrated api client previously did the HTTPConnection /
HTTPSConnection url parsing dance. In python 2.x HTTPSConnection
doesn't care about SSL certs at all. While not actually an issue for
these tests, it does mean we keep around an example in the code that
uses HTTPSConnection, which will prevent us from creating a hacking
rule to keep those out once the other 4 actual security issues with
HTTPSConnection are removed.

Destroy orig VM during resize if triggered by user

Patch I7598afbf0dc3c527471af34224003d28e64daaff introduces a
Minesweeper failure, due to the fact that it doesn't distinguish
between destroy operation triggered by the user and by the revert
resize.

This patch fixes the issue by checking the task state. If the task
state is revert_resize, the original VM doesn't get deleted.

Disable libvirt NUMA topology support if libvirt < 1.0.4

If you're not at a new enough version of libvirt, the compute service

This add a min version check before trying to get host NUMA topology

Fix the os_networks display to show cidr properly

Converting network_get and network_get_all to use objects broke
the display of the os_networks extension, because IPAddress
fields in Network objects are dumped as lists by the jsonutils
extension. We therefore must explicitly convert these object
field values to string.

The tests are updated to use objects so that we pick up bugs
like this in the future. Incorrect assertEqual parameter order
is fixed in the tests too since these are comparing dicts and
it's not fun debugging a MismatchError when the reference/actual
values are backwards.

Mask passwords in exceptions and error messages

When a ProcessExecutionError is thrown by processutils.ssh_execute(),
the exception may contain information such as password. Upstream
applications that just log the message (as several appear to do)
could inadvertently expose these passwords to a user with read access to
the log files. It is therefore considered prudent to invoke
strutils.mask_password() on the command, stdout and stderr in the
exception. A test case has been added (to oslo-incubator) in order to 
ensure that all three are properly masked.

An earlier commit (853d8f9897f8563851441108a9be26b10908c076) failed
to address ssh_execute(). This change set addresses ssh_execute.

OSSA is aware of this change request.

Update rpc version aliases for juno

Update all of the rpc client API classes to include a version alias
for the latest version implemented in Juno.  This alias is needed when
doing rolling upgrades from Juno to Kilo.  With this in place, you can
ensure all services only send messages that both Juno and Kilo will
understand.

Remove obsolete vmware/esx tools

Our Docs have updated information in and the README is stale.
http://docs.openstack.org/trunk/config-reference/content/vmware.html#vmware-prereqs

The guest_tool.py was once used a long time ago to setup
networking by pulling information from esx and setting
the OS details in the VM. This is no longer used or needed as
we have better ways to do the same using config drive or metadata service

Fix broken cert revocation

Cert revocation was broken by
32b0adb591f80ad2c5c19519b4ffc2b55dbea672.  os.chdir() never returns
anything, so this method would always raise an exception.  The proper
way to handle an error from os.chdir() is to catch OSError.

There were existing tests for this code, but they conveniently mocked
os.chdir() to return values that are never actually returned.  The
tests were fixed to match the real behavior.
