Replicate .github dir templates across all LB projects

[superkhau]

• [x] Get feedback from @raymondfeng @ritch and @cgole regarding the content of https://github.com/strongloop/loopback/blob/master/.github/ISSUE_TEMPLATE.md and update accordingly (@superkhau will do this after chatting on hangout)
• [x] Copy the entire .github dir (you want to copy both ISSUE_TEMPLATE and PR_TEMPLATES) across all LoopBack projects (see https://github.com/strongloop/loopback-triage/blob/master/repos.json)
• [x] Create a checklist as usual to the PRs
• [x] Get @superkhau to review each PR and land them accordingly
