Endpoint to See if User is Member of a Group

[rootelement]

In challenge api, we need to see if a user has access to a challenge. We have a group UUID and a member ID, but because of the security / groups and subgroups layout, it's not easy to see if a user has access to a group.

I propose providing an endpoint with a HEAD where you can just see if a user has access to a group. I'm thinking something like this:

HEAD /v5/groups/:groupUUID?memberId=12345

The response for this call should include a header that says if the user has access to that group UUID. This will prevent the challenge api side having to traverse a whole group tree of data, string matching on UUIDs.

this has been implemented and deployed on dev

@SathyaJayabal Pls verify and update QA status.

@dushyantb , the endpoint returns check = false for all cases.
Example: the below user is the member of the below group, but the api returns false
member: 40159097
group: 20000000
