Fixes messages logged on Glance plugin retries

Retry logic is now being used for both upload_vhd and download_vhd,
but nova/virt/xenapi/client/session.py still had 'upload_vhd'
hardcoded in its logged messages. This change causes it to accept the
function being used as an argument and display that.

Correct the state for PAUSED instances on reboot

If an instance is in the PAUSED state before the compute node is
restarted, it will be left in an inconsistent state (impossible to
delete and/or restart it) after the node boots again.

This patch adds a check in the periodic task sync_power_state so when
this situation is detected the instance is stopped and left in a state
from where it can be started again or deleted.

Support building wheels (PEP-427)

Universal is used to identify pure-Python module(by bdist_wheel). For
these, it is sufficient to build a wheel with _any_ Python ABI version
and publish that to PyPI (by whatever means).

Make sure "volumeId" in req body on volume actions

We should check whether the parameter "volumeId" is in request body while
attaching a volume to an instance and while swapping volume.

Fix invalid facilities documented in rootwrap.conf

The values user0 and user1 do not map to valid facility values.
local1, etc.  Using user0 results in a  pri value that does not map
back to a facility of the same name in syslog.

RFC5424 suggest values values of local0 through local7.  Setting
syslog_log_facility to one of those values results in a message with a
priority that can be mapped back to the original string value.

This fix adjusts the comment in rootwrap.conf to suggest the local
prefix instead of the user prefix.

Fix incorrect kwargs 'reason' for HTTPBadRequest

webob.exc.HTTPBadRequest doesn't have attribute 'reason', and its
__init__ method doesn't have such parameter too, so if we use such
kwargs, it will not be accepted by constructor of base class
WSGIHTTPException, then the http response body will format message
using default explanation instead of what we expected.

We should use kwargs 'explanation' instead of wrong 'reason'.

Catch InstanceNotFound exceptions for V2 API virtual interfaces

Use the common.get_instance method to get the instance object
in the V2 API virtual interfaces extension rather than call
the compute api directly. The utility function
handes InstanceNotFound exceptions and tranlsates them to HTTPNotFound
rather than letting them propagate up causing a traceback.

Fix the validation of flavor_extraspecs v2 API

"create flavor_extraspecs" v2 API does not validate the data type
of a request body. If invalid parameter is passed, an internal error
happens. If many invalid requests come, a log file would be occupied
with traceback.

In addition, it does not validate the lengths of both key and value of
extra_specs. extra_specs are stored into the instance_type_extra_specs
table, and the key and value are defined as String(255).

This patch fixes the validation code from the viewpoint of data type
and key/value length.

Fix the calls of webob exception classes

The webob exception classes has "explanation" arguments but some
methods calls the classes with invalid arguments. This patch fixes
them.
In addition, this patch changes the error handling of agent_build
_create() because the method raises AgentBuildExists exception only.
The API of v3 has already done it.

Fix HTTP methods for test_attach_interfaces

delete() method of attach_interfaces API is routed when specifying
"DELETE" as HTTP method, but some tests specify "POST". This bug
does not affect the test behaviors because the tests do not check
API router behaviors and just checks delete() method behaviors.

However, this patch fixes this bug because the bug confuses the
API router behaviors.

Replaces exception re-raising in Hyper-V

In a few cases in the Hyper-V driver classes, generic exceptions
are getting caught, logged and a domain specific exception is raised.

This creates issues in identifying the exception cause programmatically
(e.g. in unit tests).

This patch enforces the usage of excutils.save_and_reraise_exception()
