The quota list tests have a race in them where occasionally a project is
deleted in another test between the time that quota list gets a list of all
projects and it gets the quota for the projects from the service; the get
quota call fails on the non-existant project.

The quota list functional tests have been substantially re-written to
properly test the exception handling.

Nova-net requires a cells v1 configuration to run as of Ocata, but
aggregates and cells v1 are not golfing buddies, so don't let them
meet on the back nine.

Skip the aggregate add/remove host commands in the cells v1 config,
leave the others because they should work, just not be very useful.

And format things consistently.

DevStack master (as of 01May2017) no longer sets up an Identity v2
admin endpoint, so we need to skip those tests going forward and cover
them via a specific leagacy job.  This does the detect-and-skip.

This has been sporadically failing in functional tests due to the way
the volume qos spec list command calls get_associations() for each spec.
When tests run in parallel occasionally a spec from another test is present
in the list returned and is deleted before the get_associations() call is
made, causing a NotFound exception.  We should just keep going when this
occurs.

* make v1 match v2
* add tests to ensure the exception is being caught and handled

* network segment
* network service
* port
* router
* security group
* security group rule
* subnet
* subnet pool
* extension
  The extension tests were duplicated to have both compute and network
  extensions tests so the nova-net case will still exercise the extension
  commands.

Also clean up formatting from previous reviews to make the Network functional
tests look and act consistently.
