[Node Checker] Add request-time category selection

[banool]

It should be possible for users to use check boxes to enable / disable checks based on these 3 categories:

• API
• Metrics
• Noise

Currently the NHC configuration / API is not amenable to this, you cannot opt in to particular checks at request time, the checks are configured for all requests in the NHC configuration.

This issue is for the frontend component of this work.
