Instructions and review process

What is the review process and when will my changes land?

All PRs require 2 approvals using GitHub's pull request reviews.

Reviewers should be:

• Developers who understand the code being modified.
• Developers responsible for code that interacts with or depends on the code being modified.

It is best to proactively ask for 2 reviews by @mentioning the candidate reviewers in the PR comments area. The responsibility is on the developer submitting the PR to follow-up with reviewers and make sure a PR is reviewed in a timely manner. Once a PR has 2 ship-it's, no red reviews, and all tests are green it will be included in the next train.

The teamcity/dcos/test/aws/cloudformation/simple failure due to ProviderError: An error occurred (ValidationError) when calling the CreateStack operation: Parameters: [DefaultInstanceType] do not exist in the template seems to be a known problem and not caused by this PR.

🚀 Identical to Mesos 1.2.3-rc1 except for the CHANGELOG update. Good enough for me!
