Stop using `*` for imports

[jorgepiloto]

🐞 Problem

Required imports should be explicit. Nowadays, the usage of * is considered a bad practice. This type of import seems to be common across the current modules.

Knowing the big amount of interfaces and that the current API design, explicit imports would add hundreds of lines...

Considering that objects are not imported and instantiated but created through scenarios, it may be valid to keep the usage of * for simple purposes and just ignore this style check.

Closing this after fixing it in #550.
