Description of the bug

When using operator.config.set_config_option on an instance of an operator, the user would expect the config of the operator's instance to be modified in-place, which is not the case.

Steps To Reproduce

import ansys.dpf.core as dpf

op = dpf.operators.math.component_wise_divide_fc()
print(op.config.config_option_value("permissive"))

op.config.set_config_option(config_name="permissive", config_value=True)
print(op.config.config_option_value("permissive"))

new_config = op.default_config()
new_config.set_config_option(config_name="permissive", config_value=True)
print(new_config.config_option_value("permissive"))

op.config = new_config
print(op.config.config_option_value("permissive"))
