The '--hint' option for 'server create' expects a key-value pair like so:

  openstack server create --hint group=245e1dfe-2d0e-4139-80a9-fce124948896 ...

However, the command doesn't complain if this isn't the case, meaning
typos like the below aren't indicated to the user:

  openstack server create --hint 245e1dfe-2d0e-4139-80a9-fce124948896

Due to how we'd implemented this here, this ultimately results in us
POSTing the following as part of the body to 'os-servers':

  {
    ...
    "OS-SCH-HNT:scheduler_hints": {
      "245e1dfe-2d0e-4139-80a9-fce124948896": null
    }
    ...
  }

Which is unfortunately allowed and ignored by nova due to the use of
'additionalProperties' in the schema [1]

Do what we do for loads of other options and explicitly fail on invalid
values. This involves adding a new argparse action since none of those
defined in osc-lib work for us. This is included here to ease
backporting of the fix but will be moved to osc-lib in a future patch.

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.

(cherry picked from commit b866202f54afddca66a77cd989b082e193a96956)

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

Otherwise, you can hit TypeErrors on Python3.

Add "dns-domain" parameter to Network class. Also check
backend extensions and send an error message in case of
an argument (like dns-domain) is sent and the extension is
missing (dns-integration in this case).
