Hi there,

We're currently working on improving the RDO and RDO Manager CI.
As part of those efforts, I'd like to use the build-pipeline plugin
[1] to build a clear dependency flow of jobs to stay in the logic of
"fail fast" and avoid needless jobs where possible.

At a bird's eye view, it would look like this:
"Install RDO on a single node and do very minimal testing" ->
"Install RDO on multiple nodes with decent/exhaustive testing" ->
"Promote the tested set of packages in the 'passed-ci' repository"

This means we wouldn't bother doing exhaustive testing if the basic
installation or the minimal testing fails and we would only promote
the tested set of packages if the exhaustive testing passes.

What's great with the pipelines plugin is that the dependencies are
very clear and the dashboard it provides is very insightful to see
what is passing or what is failing [2].

We will eventually be moving the RDO and RDO Manager CI jobs to the
ci.centos infrastructure so knowing whether or not we can use this
plugin is important. There are other ways around doing this (with
another plugin, multi jobs) but it's not as straightforward, IMO.

Please let me know what you think,

Thanks !
