Runnable careers

Runnable saves time and frustration caused by development pipeline and the staging server by providing full-stack environments for every code branch, and any application.

Features:
- Environments are created and kept up-to-date automatically based on branch activity.
- Environments are full-stack, including replicated databases and other services needed to run your stack.
- Run end-to-end tests for every code change, including support for Selenium/Webdriver tests.
- Environment links and test results are posted on the Pull Request pages in GitHub for easier reviews.
