Skip creating and preparing project if possible

[janpio]

When testing paramedic itself, the project to be tested is always identical (unless something changed in the project setup code). This could be used to not create and prepare the project on each run maybe, to majorly speed up the test runs.

• Create project in one directory, copy it over to other directory to build and test

[janpio]

Maybe hide this behind a parameter, so it can opotionally be applied when running paramedic locally. The folder where the project is stores should contain all the params (platform, plugin(s) etc) that define how the project is built.
