Allow generating access tokens with wildcard/prefix roles

[pizerg]

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

When creating an access token it's not possible to allow wildcard or prefixes in the roles section, this might be useful in some cases where some groups are ephemeral and created dynamically.

Describe the solution you'd like

When assigning roles to a generated token, allow permissions such as webpubsub.joinLeaveGroup.[prefix]* or webpubsub. sendToGroup.[prefix]*

@vicancy @Y-Sindo are there any plans to implement this in the near future?

It would be really useful to have it implemented to handle cases such as having a "big" number of roles/groups that might hit HTTP header limits (when generating the JWT) and would increase the flexibility when designing groups structure

Hi, we're in the progress of designing and implementing the feature. We estimate that it will take two or three months to rollout the feature.
