[feature] #1902: Bare metal 4-peer setup script.

[appetrosyan]

Signed-off-by: Aleksandr a-p-petrosyan@yandex.ru

Description of the Change

Refactored scripts to be more self-contained and flexible for use in GitHub actions.

Added a version of setup_test_env.sh that does not require docker-compose and uses the debug build of Iroha.

Issue

Closes #1902.

Benefits

Can run tests using live iroha peers without use of Docker. Creates pathway to resolve #1726

Possible Drawbacks

More logic relegated to bash.

TODO

Cleanup.

Test on other configurations.
