Title: Added placeholder bag

Added placeholder bag for replacing placeholders.
Say we have a REST API and want to compare the output in Behat. We want the output to contain an id which is generated dynamically. In the scenario we can put a placeholder like f.e. `USER_ID` and then replace it with the usage of placeholder bag in the step itself before comparing.
