feat(cli): control progress output style with --progress=bar|events

[shivlaks]

Since the new deployment monitoring has been problematic on environments such as CI,
adding a switch called progress to allow users to set their deploy output display preference.

Supported values are bar and events. The default deployment display mode includes the
progress bar.

The workaround of adding -v to display the stack event history includes a lot of
undesired output and users have expressed that it includes a lot of noise.

If the key progress exists in user settings (~/.cdk.json) or project settings (cdk.json),
users will not need to specify it on every deploy and can set their desired default once.

closes #8696

To improve discoverability of the various options and allow future modes let's use an enumeration:

--progress=bar (current behavior)
--progress=events (old behavior)

Got it, thanks!

@shivlaks Can you please provide an example on how to set this in ~/.cdk.json globally? I can't seem to get it right.

Thanks!
