Merge #19877: [test] clarify rpc_net & p2p_disconnect_ban functional tests
47ff5098ad5ea2c20ea387f99940a7cde6c80789 [test] Clarify setup of node topology. (Amiti Uttarwar)
0672522aedd3760c30b8740c7e9487f00bf9dfeb [move-only, test]: Match test order with run order (Amiti Uttarwar)

Pull request description:

  small improvements to clarify logic in the functional tests
  1. have test logic in `rpc_net.py` match run order of the test
  2. remove `connect_nodes` calls that are redundant with the automatic test setup executed by the test framework

  Noticed when I was trying to debug a test for #19725. Small changes but imo very helpful, because they initially confused me.
