Thanks to the work of Dean and others we have a pretty solid plugins/extras
support in Devstack. People can add new features in devstack within just a
single file and that add a whole new feature or driver to devstack.

It seems that there is quite a bit of people who wants to have those extras
plugins/features in the default devstack core because it's way more
convenient for their users.

The policy has been mostly (and correct me if I am wrong) that things which
are not tested in the gates cannot be in core devstack.

What about having a plugin structure for devstack assuming a standard
directory structures which devstack would download and use automatically.

For the implemention I was thinking about something like this in our
local.conf :

enabled_services blah_feature:

and that repo gets downloaded and used automatically.

I understand that it is just a shortcut since curl -O
in extras.d would work as well but maybe that would make people more
confortable not having to be in core devstack and tell their users easily
how to test a feature/driver with Devstack?
