App update on the cli is broken

[Swati Dewan]

The app update command on the cli is broken. It throws the error: "ERROR: Your request could not be handled because of a problem in the server." On taking a look at solum-api logs, this is the stack trace I see:

Also, using the solum app help command on the cli, help text for the update command is not shown.
