Roger's suggested changes to PR template

These are ideas Roger had for the template. I'll let him elaborate but I think the gist of it is that more people are checking against the Jira, and ensuring we're not blocked waiting for IPs to complete code review before merging.
Personally I don't think the IP checklist should be in there at all, instead developers and software engineers mentoring IPs should encourage them to go check through and comment on PRs. They're fully exposed to the code review process when they submit their own Pull Requests, so it won't be that they don't learn how this works.

I agree making an optional +1 confuses the issue completely.
