DEPS: Keycloak python client has pkg_resource deprecation warning

[iameskild]

Keycloak python client has pkg_resource deprecation warning which can cause tests to fail. Using an older version of setuptools gets around the deprecation warning but ultimately we would prefer the deprecation to be handled by the Keycloak python client.

Upstream issue: marcospereirampj/python-keycloak#477

The alternatives for now are to pin setuptools to an older version (63.4.3 seems to work) or filter these deprecation warnings.

There is an open PR to fix this marcospereirampj/python-keycloak#483
