Interpolate params inside of params.
This patch enables parameters to be expanded inside of other parameters. For
instance:
- job-template:
name: '{value-stream}_{pipeline_type}_foo'
builders:
- shell: 'echo "I am foo job!"'
publishers:
- trigger-parameterized-builds:
- project: '{downstream}'
current-parameters: False
condition: ALWAYS
git-revision: True
- job-template:
name: '{value-stream}_{pipeline_type}_bar'
builders:
- shell: 'echo "I am bar job!"'
publishers:
- trigger-parameterized-builds:
- project: '{downstream}'
current-parameters: False
condition: ALWAYS
git-revision: True
- job-template:
name: '{value-stream}_{pipeline_type}_baz'
builders:
- shell: 'echo "I am baz job!"'
publishers:
- trigger-parameterized-builds:
- project: '{downstream}'
current-parameters: False
condition: ALWAYS
git-revision: True
- job-group:
name: 'pipeline2'
pipeline_type: 'p2'
jobs:
- '{value-stream}_{pipeline_type}_foo':
downstream: '{value-stream}_{pipeline_type}_bar'
- '{value-stream}_{pipeline_type}_bar':
downstream: '{value-stream}_{pipeline_type}_baz'
- '{value-stream}_{pipeline_type}_baz':
- job-group:
name: 'pipeline1'
pipeline_type: 'p1'
jobs:
- '{value-stream}_{pipeline_type}_baz':
downstream: '{value-stream}_{pipeline_type}_bar'
- '{value-stream}_{pipeline_type}_bar':
downstream: '{value-stream}_{pipeline_type}_foo'
- '{value-stream}_{pipeline_type}_foo':
- project:
name: derp
jobs:
- 'pipeline1':
value-stream:
- experimental
- staging
- 'pipeline2':
value-stream:
- experimental
- staging
- production
Prior to this commit, the setup above was not possible because the `downstream`
defined as parameters to be passed to job templates in the job groups would not
have the `value-stream` and `pipeline-type` parameters interpolated. The
trigger-parameterized-jobs `project` value for each of the 15 jobs created with
this setup would all look something like `{value-stream}_{pipeline_type}_foo`
which does not actually point to any particular job.
The only way I was previously able to specify a downstream job with parameters
was to put the `{value-stream}_{pipeline_type}_foo` string directly in the
job-template which meant that job templates were statically bound to each
other--I had no reasonable way to re-order or easily select subsets of the jobs
at the job-group or project level as can be seen here in the difference between
`pipeline1` and `pipeline2`.

JJB also supports interpolation of parameters within parameters. This allows a

little more flexibility when ordering template jobs as components in different

projects and job groups.
