Environment#generate_slug

An environment name is not necessarily suitable for use in URLs, DNS
or other third-party contexts, so provide a slugified version. A slug has
the following properties:
  * contains only lowercase letters (a-z), numbers (0-9), and '-'
  * begins with a letter
  * has a maximum length of 24 bytes (OpenShift limitation)
  * cannot end with `-`
