cdk: cdk CLI should abort in case an invalid option is provided

[saste]

Describe the bug

cdk COMMAND should fail in case a provided option is not known.

For example cdk synth --foo-bar or cdk synth --output-file out.json should fail so that the user is able to spot a mistake in the command.

Expected Behavior

The command should fail in case a specified option is unknown.

Current Behavior

The command ignores the failure and proceeds, the mistyped or unknown option is ignored.

In case of typos, the user will realize later, only after some investigation.

Reproduction Steps

Run cdk synth --foo-bar or any command with an unknown/mistyped command line option.

Possible Solution

Implement a check in case of invalid options, or at least a big warning so that the user can notice the issue.
