Extend Authd existent tests with new scenarios from the force options configuration

[palaciosjeremias]

As part of #2050 we need to extend the existing tests with new scenarios:
As we identified, we need to extend the test cases of:

• test_authd_local.py
• test_authd_worker.py
  And add testcases for:
• Agents key hash.
  • Key_hash enabled
    • Agents with existing key
    • Agents without existing key
  • Key_hash disabled
• Verify that a worker sends a force_option block in null to delegate the configuration to the manager.
• Key requests on local_server with a specified force_option block.
• Key requests on local_server without a specified force_option block.
