Time-based role bindings

[weisdd]

Is your feature request related to a problem? Please describe.
In some cases (like for production environment), there could be organization policies in place restricting the amount of time a certain level of access can be granted to a user. Some cloud providers like Azure offer JIT-access (Just-in-Time), though it'd be great to have something more generic.

Describe the solution you'd like
Not sure if it's within the scope of the project, but it'd be interesting to see time-based role bindings.
Say, I grant elevated access to a user now and want it to get revoked (through deletion of RoleBinding/ClusterRoleBinding) at 10 am this Friday. I don't expect it all to be super-precise, just a few minutes-wide window would be good enough.
As a variation, there could be more flexible schedules with both start and end dates present.

Describe alternatives you've considered

• scheduled pipelines;
• reminders to adjust RBACDefinition.

I believe this is a duplicate of #204

(And still a great idea)

@sudermanjr Indeed, thanks for pointing that out! I guess, when I was searching for discussions around this idea, my set of keywords was too specific, so missed #204.
Anyway, great to see that it's something on the radar, just waiting for community contributions. I'll see if it's something I could work on in the coming weeks (mostly depends on my work load).
