The previously introduced token caching mechanism [1] reduces token
requests to subclouds and also effectively handles Keystone endpoint
caching, as the endpoint catalog is cached alongside tokens.
This commit applies the endpoint_cache logic to DCAgent.

Test Plan:
- PASS: Manage a healthy subcloud and verify the audit is working
as expected.
- PASS: Execute a sw-deploy orchestration and check audit works
as expected.
- PASS: Manage a healthy subcloud and verify Fernet keys rotation and
audit sync afterward.
- PASS: Check token validation and expiration after 1h.
- PASS: Check that Keystone requests are still being made only once
per cycle.
