Add sha filter to list pipelines

What does this MR do?

Allows pipeline list to be filtered by commit sha

Are there points in the code the reviewer needs to double check?

Confirm there are no performance problems with this.

Why was this MR needed?

Using the API it is easy to find the commit status of a commit (sha), but it is difficult to find the pipelines run for a commit. Finding the pipeline id is necessary to determine job id, and then the job trace.
