Add a platform_group_assignment resource

[SKY-Mark-Rhoades-Brown]

Is your feature request related to a problem? Please describe.

The documentation for JFrog Platform REST API shows that there is a Add or Remove a Group Member method. This would enable us to have a resource type that allows a 1-2-1 mapping between users and groups.

Using this new resource allows for independence of the creation of users and groups and treats the assignments separately. This would result in more items in state, but it allows for fine and granular control, and introduces a single level of responsiblity.

Describe the solution you'd like

• I would like terraform resource that allows an assignment of one user to one group.
• When the resource is created, it would add the group membership.
• When the resource is deleted, it would delete the group membership.
• The resource should detect if the resource is deleted.

Describe alternatives you've considered

Adding users to groups and adding groups to users. This is not ideal.

@SKY-Mark-Rhoades-Brown Thanks for the suggestion. We have similar concept in the Project provider (project resource with project_repository, project_user, etc.) to solve the same catch-22 issue, so this will be consistent and make lots of sense.
