Turn off staging after hours

[cweibel]

Changes proposed in this pull request:

• This is a similar change as the previous PR, it adds a timer and job that turns staging off after 6PM PT.
• A stemcell update, release update or changes to the pipeline will trigger the environment to turn back on, this is a desired behavior. If needed, can add a "turn on" timer that triggers the "deploy-" which will redeploy the environment
• Save more $$$ on EC2 costs. As long as the RDS db that backs the deployment is left alone, the deployment can remain turned off indefinitely but no scaling events will occur.

Things to check

• For any logging statements, is there any chance that they could be logging sensitive data?
• Are log statements using a logging library with a logging level set? Setting a logging level means that log statements "below" that level will not be written to the output. For example, if the logging level is set to INFO and debugging statements are written with log.debug or similar, then they won't be written to the otput, which can prevent unintentional leaks of sensitive data.
