Add ios_static_route module (ansible#25527)

* Add ios_static_route module

* Add ios_static_route integration tests

* Add platform agnostic integration tests for IOS

* Replace unicode function to ansible module_utils to_text

* Add collections handling logic

* Add integration tests for collections

* Make collections and prefix mutually exclusive

* Add net_static_route integration tests for collections

* Do not store load_config return value, as it returns nothing
