faf02674b3refactor: Set TestNode.cli only after RPC is connected (MarcoFalke)fae376cafbrefactor: Inline get_rpc_proxy (MarcoFalke)fa00c7c7a4test: Allow rpc_bind.py --usecli (MarcoFalke)fa8f25118crefactor: Use create_new_rpc_connection in wallet_multiwallet.py (MarcoFalke)fa3ae6c7d3test: Allow feature_shutdown.py --usecli (MarcoFalke)fa2a3683d5test: Allow mining_getblocktemplate_longpoll.py --usecli (MarcoFalke)fa37c6a529test: [move-only] Extract create_new_rpc_connection (MarcoFalke) Pull request description: Some tests disallow to be run under `--usecli`. This reduces the coverage and risks that bugs in the bitcoin-cli go unnoticed. The commits should be self-explanatory and can be reviewed and tested one-by-one.
