Add a login script without any cf push

[adborden]

I want to be able to run arbitrary cf commands like cf run-task. To do this I have to run all the login commands myslef. If this was a script, I could use it and it could be re-used in cf_deploy.sh.

I feel like we've got a good opportunity to turn this into the swiss-army knife of a docker image for 18F folks who want to use CF-cli within CircleCI. See my comment in #7 around this.

This would probably get cleared up once #11 gets addressed. I like the idea of this image only containing the plugins we need and becoming more of a Bring Your Own Scripts with either examples or scripts folks could call if they really wanted to not write anything custom

We could include plugins like

• Antifreeze
• CF Recycle

and scripts like

• first_time_deploy.sh
• restage_application.sh
• run_worker.sh
