Set up webhooks for boilerplate

[danielwatson6]

Changes to boilerplate code should occur in the boilerplate repo in a way that we can pull them here while keeping the repos separate.

We don't need webhooks, the above thread is exactly what we're looking for.

@abdullahzameek can you fork tensorflow-boilerplate, issue a PR with the latest run.py and boilerplate.py files here?

Then let's find a way to make this repo a fork of tensorflow-boilerplate in the least destructive way possible (i.e., let's try to keep the issues, commit history, projects, etc)
