project templating system
On setup where Zuul ends up triggering hundreds of projects, you end up
having projects using roughly the same pipeline/jobs. Whenever one want
to add a job in all the similiar project, he has to edit each project
one by one.
To save some precious time, this patch introduces the concept of project
templates. It lets you define a set of pipeline and attached jobs
though the job names can be passed parameters defined on a per project
basis. Thus, updating similiar projects is all about editing a single
template.
A basic example is provided in the documentation.
The voluptuous schema has been updated. It does check whether all
parameters are properly passed to a template but does NOT check whether
the resulting job name exist.
The parameter expansion in templates is borrowed from Jenkins Job
Builder (deep_format function). It has been tweaked to also expand
dictionary keys.
Layout test plan:
$ nosetests -m layout --nocapture
Test layout file validation ...
<...>
bad_template1.yaml
required key not provided @
data['projects'][0]['template']['project']
bad_template2.yaml
extra keys not allowed @
data['projects'][0]['template']['extraparam']
good_template1.yaml
ok
<...>
$
A basic test hasbeen added to verify whether a project-template properly
triggers its tests:
$ nosetests --nocapture \
tests/test_scheduler.py:testScheduler.test_job_from_templates_launched
Test whether a job generated via a template can be launched ... ok
