[RFD]: Move permissions to keycloak

[c0rydoras]

Your proposed enhancement

Currently permissions are managed by django, i would like to move all permission things to keycloak (e.g. with groups) and have it as the single source of truth.

Examples:

• https://github.com/adfinis/mysagw
• https://github.com/adfinis/outdated

I'm unsure how possible this is, please comment on it :)

Enhancement Impact

Keycloak becomes single source of truth for permissions
