chore: remove orphaned pytest config-generation code

The generate-test-configs subcommand and its scaffolding were only ever
invoked by the removed pytest suite (#3076). Removes the CLI command and
its testing module, the CLI_FOR_PYTEST port seed, the now-dead
TOTAL_DEFINED_PORTS constant, and the unused p2p_keypairs parameter of
generate_test_p2p_configs.
