Simplify test checks and fixtures:

Remove default SSH key path.
Replace multiple fixtures for file generation with single function.
Rename references to keyword modules.
Update pytest test cases to be consistent with new keywords.
Remove gas balance checks from container operations.
Add logic to run initial gas transfer only if storage is not free.
Remove robot testsuites for s3 and http gateways.
S3 and http tests are covered and will be maintained in the future in pytest.
