Neutron has now various subprojects and some of them would like to
implement Horizon supports. Most of them are additional features.
I would like to start the discussion where we should have horizon support.

Horizon team introduced a plugin mechanism and we can add horizon panels
from external repositories. Horizon team is recommending external repos for
additional services for faster iteration and features.
We have various horizon related repositories now [1].

In Neutron related world, we have neutron-lbaas-dashboard and
horizon-cisco-ui repos.

[Possible options]
There are several possible options for neutron sub-projects.
My current vote is (b), and the next is (a). It looks a good balance to me.
I would like to gather broader opinions,

(a) horizon in-tree repo
- [+] It was a legacy approach and there is no initial effort to setup a repo.
- [+] Easy to share code conventions.
- [-] it does not scale. Horizon team can be a bottleneck.

(b) a single dashboard repo for all neutron sub-projects
- [+] No need to set up a repo by each sub-project
- [+] Easier to share the code convention. Can get horizon reviewers.
- [-] who will be a core reviewer of this repo?

(c) neutron sub-project repo
- [+] Each sub-project can develop a dashboard fast.
- [-] It is doable, but the directory tree can be complicated.
- [-] Lead to too many repos and the horizon team/liaison cannot cover all.

(d) a separate repo per neutron sub-project
Similar to (c)
- [+] A dedicate repo for dashboard simplifies the directory tree.
- [-] Need to setup a separate repo.
- [-] Lead to too many repos and the horizon team/liaison cannot cover all.

Note that this mail is not intended to move the current neutron
support in horizon
to outside of horizon tree. I would like to discuss Horizon support of
additional features.
