Avoid use a certain template if the user doesn't need a specific module

[ARR552]

Avoid use a certain template if the user doesn't need a specific module.
For instance, if a user doesn't want to use mongodb in his project, there should be an option to disable it and not use the template. Now, what it happens is that the template is showed anyway. Then, the user has to remove the part of the code that uses mongodb and the mongo db files.
