defaults for git_url and git_branch are not written upon initialization of pipelines via the command line oc pipeline

**Is your feature request related to a problem? Please describe.**
I am always frustrated when i click on "start" for a pipeline and the git_url and git_branch are not filled with default values. I just ran the oc pipeline command and filled in project on my terminal when i was in the correct branch, the pipeline should reflect that - it would save me time

**Which persona(s) does this feature benefit (e.g. developer, SRE, etc)?**
developer,sre

**What is the impact of not having this feature? What will be the benefit of having this feature?**
benefit is to save the dev/sre time to have to lookup the git url or branch name - two fewer mistakes to be made

**Describe the solution you'd like**
when defining the oc pipeline, record the git url and branch in the pipeline just like the scan-image is recorded and retained. This allows a 'start' of a new pipeline run to be faster

**Describe alternatives you've considered**
no alternative - leave it the way it is if rejected
