Zeebe client token not being refreshed

[cdonuut]

Describe the bug

The bearer token is not being refreshed after it has expired after ~5 minutes. The new common authentication library is used in the case where the token is not being refreshed.

To Reproduce

First Step: Setup Camunda Platform with Keycloak Authentication
Second Step: Connect a Worker using Common Authentication
Third Step: Run the worker and wait 5 minutes

Expected behavior

The token is refreshed before it expires, but in this case it does not.
