feat(cli): add cmds to clear workspace rules

This commit adds three new commands, clear-workspace-rules,
clear-named-workspace-rules and clear-all-workspace-rules, to allow
users to remove workspace rules at runtime.

These commands do not distinguish between initial or persistent
workspace rules. If there is a clear use case for this distinction, this
decision can be revisited at a later date.
