The release for VECMAtk released on M12

This is the release targeted for the M12 release of [VECMA VVUQ Toolkit](https://www.vecma-toolkit.eu/)
This is the first release adjusted for the VECMA project that introduces two new features supporting the VECMA UQ analysis scenarios:
- New LocalManager class, which allows to start QCG Pilot Job Manager directly from a python code.
- The local, testing mode of execution which allows to define virtual resources and may be useful e.g. for tests performed on users' laptops outside the Slurm queueing system.

This version provides two new functionalities:
* the `LocalManager` class, which allows to start QCG Pilot Job Manager directly from a python code,
* the testing mode of execution which allows to define virtual resources and may be useful e.g. for tests performed on users' laptops.
