Improve module auto detection

[gzsombor]

Currently, if a project is not generated with JHipster-Lite - maybe, because it was generated with Classic JHipster - the tool could not detect, that certain behaviours are already there, so re-running is not needed.
Like, if there is already a pom.xml, the maven initialization is not strictly needed.
It would be nice, if every module could provide an auto-detection feature, which could be called by JHLite, whenever

• a project is opened
• all of the module's dependency are satisfied

to check, if that module should also be considered as executed.
So for example, the MAVEN_JAVA module could check for pom.xml, the MAVEN_WRAPPER could check if mvnw script is there, etc.
