Fix various things so the functional tests will work under python3:

- A hashlib.md5() can only be update()d with an encoded string in py3.
- There's no dict.iteritems(), change to dict.items() (which is already
  an iterator).
- Open temp files with 'w+' mode rather than the default 'w+b' (as an
  alternative to encoding all the write and expected-read payloads as
  bytes).
- (This is a weird one) Explicitly raise SkipTest from unittest (rather
  than unittest2, which is where cls.skipException landed). Not sure why
  this is busted, but this moves the ball.

Conflict/issue with raising SkipTest on this branch.

Includes squash of:
Before writing object data to stdout, re-open it in binary mode

Otherwise, you can hit TypeErrors on Python3.

VolumeBackupsRetore object has '_info' attribute
which contains the output data of the restore
command which should be returned instead of the
'VolumeBackupsRestore' object.

Compute API version >= 2.37 requires a 'networks' value in
the server create request. The novaclient CLI defaults this
to 'auto' if not specified, but the novaclient ServerManager.create
python API binding code does not, as it wants clients to be explicit.

For the purposes of the OSC CLI, we should follow suit and if the
user is requesting OS_COMPUTE_API_VERSION>=2.37 without specific
nics, we should just default to 'auto'.

This patch aims at fixing the broken gate jobs because of
cinder and glance patches [1], [2], [3] and [4].

* Remove parameter `--source-replicated` to drop volume
  replication v1 support
* Address some timing issues with volume transfer requests
* Only run Image v1 tests when the test cloud has v1 available
* Get tolerant of unexpected additional attributes being
  returned in Image data

Knowing what services and what versions of those services exist on a
cloud isn't always a spectacular experience. Add a command that will use
get_all_version_data from keystoneauth to produce a report of the
available services and the version info for each service.
