What's the user value of this feature request?
This would make the new space supporter role type in CAPI applicable to V8 CLI users.

Who is the functionality for?
V8 CF CLI admin users

Describe the solution you'd like
Currently, the cf CLI command set-space-role returns an error when SpaceSupporter is provided as an argument. We would ideally like to expand the permitted role types list to include a case insensitive spacesupporter type. The rest should be handled by CAPI.

Additionally the help text for this command to include SpaceSupporter under the list of expected roles with a note that this role is still under active development and not ready for use.
