Toolkit - Move from replaceAll to true template engine
The templates used by the Toolkit start to require some logic. For example the NamingScheme tag requires to expand a Set to multiple lines.
Currently we put that logic in the java class and use a replaceAll but it would be better to put that logic in the template itself using a true template engine. For example the NamingScheme tag would be replace with a foreach loop that expand the Set in the template. Also this would help factorizing the code by putting common tag and their value into a more global context set for the template engine
Switching should be simple as we are already using standard template tags for our variable.
Ofc the template engine needs to be light and fully available in a jar or any format requiring no installation to avoid adding new dependencies. For example https://github.com/HubSpot/jinjava or http://jtwig.org/
This is a "nice to have" feature so we should do it when we have more time.
