This will be a two part fix -- one for subscription-manager and one for candlepin.

On candlepin, a BadRequestException was being created and thrown with a List.toString() as the message which produced the "[..., ...]" message string. Also, the messages in that list were being duplicated as seen above which isn't very useful.

The Fix: Invalid overrides are collected in a set and a single message will be returned in the following format:

"Not allowed to override values for: NAME1, NAME2, ..."


Changes were required in subscription-manager to changed the error code and to print to stderr.

As requested by jsefler (irc), it will now return a code of 1 instead of 255, and will write to stderr.

VERIFIED: The feedback message is now nicely unwrapped and rendered uniquely.

For the sake of consistency with exitCode/stdout/stderr behavior from other subscription-manager commands, I would suggest that we keep the exitCode of 1 (which indicates the call was not completely successful (usually exitCode=0), but we were also not crashing and burning (usually exitCode=255)).  However, let's move the feedback message to stdout since stderr is usually accompanied by exitCode 255.

FAILEDQA: Move the message from stderr to stdout.

Awaiting PR Review:

https://github.com/candlepin/subscription-manager/pull/844

Print error to stdout, and exit with code 1.
