Adds a new 'troubleshooting' function which encapsulates the things we might want to do when something bad happens. Typically this is echo'ing a simple message and launching a bash shell. The new troubleshooting function also makes use of a new 'troubleshoot' kernel param which if specific will allow you to hang the deployment process and interactively debug the deploy_ramdisk via a bash shell on a console. Troubleshoot is disabled by default. Fixes LP Bug #1191043. Change-Id: I2cba8a9674075ba7e420027d40ef8cbe756cf07e
