Ok, I have a POC that has worked end to end in our CI environment[1], 
there are a *LOT* of workarounds in there so before we can merge it I 
need to clean up and remove some of those workarounds and todo that a 
few things need to move around, below is a list of what has to happen 
(as best I can tell)

1) Pull in tripleo-heat-template spec changes to master delorean
We had two patches in the tripleo-heat-template midstream packaging that 
havn't made it into the master packaging, these are
https://review.gerrithub.io/241056 Package firstboot and extraconfig 
https://review.gerrithub.io/241057 Package environments and newtork 

2) Fixes for instack-undercloud (I didn't push these directly incase it 
effected people on old versions of puppet modules)

3) Add packaging for various repositories into openstack-packaging
I've pulled the packaging for 5 repositories into 

I havn't imported these into gerrithub (incase following discussion we 
need to delete them again) but assuming we're in agreement we should 
pull them into gerrithub)

4) update rdoinfo
If everybody is happy with all above we should merge this, all of the 
packages needed will now be on the delorean master repository

5) Move DELOREAN_REPO_URL in tripleo-ci to a new delorean repo that 
includes all of the new packages

6) Take most of the workarounds out of this patch[1] and merge it

7) Reorg the tripleo ci tests (essentially remove all of the bash 
element based tests).

8) Pull instack, instack-undercloud, python-rdomanager-oscplugin, 
triple-common, tuskar-ui-extras and maybe more into the upstream gerrit

 From here on the way to run the tripleo will be to follow the 
documentation in instack-undercloud, we should no longer be using 
devtest, this means we've lost the automation devtest gave us, so we 
will have to slowly build that up again. The main thing we have gained 
is that we will now be developing upstream all parts of how we expect 
deployers to use tripleo.

- we will still have dependencies on tripleo-incubator we need to remove 
these (or move things into other repositories), essentially were 
finished with this process once we're no longer installing the "tripleo" 
- The new CI (as is) is running on Fedora jenkins nodes but building 
(and deploying) centos images, we also discussed that some people would 
want to develop on Fedora we will have to create a Fedora job as well 
(which I'm sure will involve the need for adding Fedora support into 

Everything in the first 4 steps is ready to go now, once done we can 
investigate moving DELOREAN_REPO_URL and remove the workarounds from the 
CI patch.
