fix: container timeout issue and new environment variables

[raph-luc]

Changes:

• Fixed issue related to the container launcher not recognizing timeout settings coming through launch_fluent. Now the container launcher respects the start_timeout argument, and the container_dict["timeout"] argument is marked as deprecated
• Now when a container launch times out, it will attempt to stop the container. I noticed during the tests that timeout or failure during launch were causing zombie containers to be left behind. Now that should not happen anymore
• test_unsuccessful_fluent_connection now works for containers as well and tests that their timeout config is working properly
• New test_container_timeout_deprecation and test_container_timeout_deprecation_override for testing the deprecation behavior
• Support for new PYFLUENT_FLUENT_LAUNCH_TIMEOUT and PYFLUENT_FLUENT_AUTOMATIC_TRANSCRIPT env vars - were useful previously for testing/development
• Convenience env_var_to_bool method to get the value from an env var and return the Boolean that represents it:
  

  pyfluent/src/ansys/fluent/core/utils/__init__.py

  Lines 61 to 67 in 1b34713

  	def env_var_to_bool(var_name: str, default: str = "false") -> bool:
  	"""Converts environment variable to boolean. By default, returns 'False' if the variable is not set."""
  	value = os.getenv(var_name, default).strip().lower()
  	if value in ("0", "off", "false", "no"):
  	return False
  	else:
  	return True

  • Refactored code to make use of env_var_to_bool where it makes sense
