Add the health_check gem end expose the health_check route
This adds a health_check controller on
/health_check (.html, .json ,.xml)
health_check/checktype (.html, .json, .xml) for example
By default it checks the database, and cache.
The endpoint is only accessible if you pass a valid health check access token. A new page in the admin section titled
Heath Check has been added in order to show the current token and allow you to reset it.
