Patch release -- bug fixes and improvements

A couple of bug fixes and improvements to the user experience have been made to the CLI.

• unsubmit command will let the user know that it does not take any arguments if arguments are given.
• Error messages from upgrade command have been improved along with a longer timeout for upgrade.
• -v global flag has been removed as it was never working as intended. We've also fixed the -verbose output.
• Paths in the configuration file will now be absolute paths only.
