Remove Python 2.6 backwards compatibility code
Python 2.6 is no longer supported in cinder as of kilo. The code in the
project that is specifically for compatibility with 2.6 is therefore no
longer required.
This commit removes code referenced as being required specifically for
compatibility with Python 2.6.
This commit removes:
- total_seconds from cinder/utils.py
- TestCase.assertGreater from cinder/test.py
- TestCase.assertGreaterEqual from cinder/test.py
- StorwizeSVCDriverTestCase.assertLessEqual from
cinder/tests/test_storwize_svc.py

Add limited retype support for rbd
This patch enables limited retype support for rbd. In addition to
basic retyping between volume types that only differ in their name,
retyping between volume types that imply a change of the qos_specs
are supported. This hence allows to adapt the quality-of-service
settings of a volume after its creation.
All other changes, such as host migration, change of encryption or
changes of settings as defined by the extra_specs are not supported
by this commit and left for later patches.

Add iSCSI Target objects as independent objects
This patch is a step in decoupling the target
methods and the Volume Driver's Control methods.
This adds the targets directory and the new target objects
that we use with the exception of IET (follow up for that later).
TgtAdm and LIO drivers have been tested with the new LVM object.
All existing drivers are still able to be specified and use the
same objects and code-path they were using previously. New
connector objects are only used when specifying the new driver.
Next step will be mapping current ref LVM driver to the new
LVM object and target model and continued work on the unit-tests.
After that mark the "old" methods and objects as deprecated
and we can then begin working on some other improvements.

Match mock.patch decorator with appropriate param
mock.patch and mock.patch.object can be used as decorators for mocking
within the scope of the function they decorate. When there are multiple
decorators it is important the function parameters relate to the
corresponding patch objects i.e. that the parameter order matches the
decorator order.
It is easiest to explain this with an example:
So the decorator closest to the function definition must correspond to
the first (left-most) patch parameter. Note, if the decorator is given a
third argument, the kwarg new, then the decorated function is not
passed an extra argument by that decorator.

Brick LVM: LV not found logging and error handling
Fix up two things in get_lv_info/get_volume:
1. ProcessExecutionError should be handled where we call the

querying a VG.
2. Not found errors should be logged as info and not warning

a problem).

Fix calls to assert_called_once in unit tests
Mock has a method called assert_called_once_with to check that a mock
was called and the arguments it took were as expected. Mock does not
have a method called assert_called_once and calling it just creates a
mock bound to that name. This means that not only is nothing tested
when assert_called_once is used, the tests also don't warn about this.
This commit attempts to address this in two ways:
- all occurrences of assert_called_once are replaced with a real
assertion.
- the hacking check that nova uses to guard against this has been
copied to cinder's local hacking checks.
Fixing the assert_called_once issues also highlighted other mistakes
in certain tests which were addressed to make the tests pass.
Due to the nature of mock, this issue is also possible if a method is
misspelt or just mistakenly used and so the hacking check is only
addressing one very specific case. That said, it does appear to be a
common mistake and so is worth singling out.

Add ability to create volume from image by image name.
Some cli commands allow specifying an image by either
its name or its ID. Creating a volume from an image
currently requires knowing the image ID. The request
was made to add the ability to create a volume using
the image name instead.
This patch adds the ability to accept either name or ID.
It will attempt to locate the image based on this input
and fail if neither can be matched. If found by name, it
will also verify there are not multiple images of the
same name. If this is the case it will require using the
ID to be explicit.
Will update python-cinderclient in a separate patch once
this has been merged to allow ID or name.

Fix exception message formatting
If the exception class made a reference to the "message" field in
its format string, it would be overriden with the value of the
"message" argument itself. It is now possible to use the "message"
field and preserve the desired message formatting. Test cases
provided.
The backing VM corresponding to a volume is cloned during create volume
from another volume, snapshot or image. The backing VM is also cloned
during retype and backup restore. Currently, the target ESX host is
unset while calling vCenter CloneVM_Task API and hence the source ESX
host is used as the target. If the destination datastore returned by
the datastore selection logic is not accessible to the source host,
clone fails. This patch fixes the problem by setting the target ESX
host (returned by datastore selection logic) while invoking clone.

PureISCSIDriver needs to disconnect hosts before deleting volumes.
Some error conditions can cause a situation where the volume is
