REST API for creating PipelineRuns

[jessm12]

Under this issue add a REST API endpoint that will take parameters and create a new PipelineRun for a specified Pipeline

When creating a new PipelineRun the information that will need to be provided to the POST method is as follows:

• The name of the Pipeline to use for that PipelineRun
• Information relating to the PipelineResources for a PipelineRun, if required
• Information relating to the repository for that PipelineRun
• Helm and Registry secret names, if required

The request will be namespaced and this is the namespace that the PipelineRun will occur in

I've worked on this too with @jessm12 and we should have a PR coming up soon for folks to try and test 😸
