This post will be a living document where I will detail how TripleO developers can initially provision and iterate quickly while working on service upgrade tasks the new fast-forward upgrade feature for in TripleO Queens.
Initial environment
This section details how to configure the initial environment with specific undercloud (UC) and overcloud (OC) versions and layouts using tripleo-quickstart.
Newton UC & OC
This basic combnination is required for end to end testing of fast forward upgrades:
$ bash quickstart.sh -R newton $VIRTHOST
Note however that the following changes are required so that vbmc is used by the undercloud instead of pxe_ssh (removed in Pike):

Master UC & Newton OC
This combination is a useful starting point for developers looking to work on tripleo-heat-templates changes for a given service:
$ bash quickstart.sh -R master-undercloud-newton-overcloud $VIRTHOST
The master-undercloud-newton-overcloud release config is introduced by the
following change:

Master UC & Newton OC with only Keystone deployed
https://review.openstack.org/#/q/topic:keystone_only_overcloud
$ bash quickstart.sh -w $WD -t all -R master-undercloud-newton-overcloud \
-c config/general_config/keystone-only.yml \
-N config/nodes/1ctlr.yml $VIRTHOST
