Is your feature request related to a problem? Please describe
Currently, there is no possibility to discover all members of a kit.

Describe the solution you'd like
A possibility to fetch a list of users that are members of a kit.

Describe alternatives you've considered

• This could be done by adding a members field to a kit containing an array of username of each member (or the id of each kitMembership).
• Or by adding a kits/{serial}/members endpoint that would return a list of username.
