incorrect user context

Environment:

• Kea version: 1.6.0
• OS: [ linux]

#15536: Kea API - Configuration - config-set removes additional configuration https://support.isc.org/Ticket/Display.html?id=15536

ok, I've checked this. And I can confirm that there is weird issue.

when user context is send to kea like this: "user-context": {"comment": "something"} indeed that "comment" is configured in subnet level - which is wrong BUT if you use other word than "comment" it works correctly e.g.: "user-context": {"any-other-word-than-comment": "something"}

We need gl issue for this, maybe there is a reason to treat 'comment' differently that I am not aware of.

bottom line: easy work around is: use anything else than "comment" as parameter name.
