Implement pipeline overview page

I'm looking at implementing a redirect from the old webpage to the new one.

@roneil Would it be simple to implement a page with the URL: https://lhcb-analysis-productions-preview.web.cern.ch/pipelines/?id=3172586

Initial thoughts:

1. This could just be a table view like the main /pipelines/ page which is filtered to show only the productions which are part of 3172586.
2. The #3172586 link at the top of this page could link to it https://lhcb-analysis-productions-preview.web.cern.ch/pipelines/?id=3172586&prod=D02HH_Practice
3. Even better yet would be if it could automatically redirect to /pipelines/?id=3172586&prod=D02HH_Practice if there is only one production for the given pipeline ID. (Perhaps with a redirect=False parameter to avoid 2 creating a confusing loop)
