baseclasses obs.py and observationoperator.py are now used in the Random ObsOperator project

See merge request ctdas/CTDAS!14

This commit will allow the basic CTDAS code to run, using baseclasses obs.py, observationoperator.py, pipeline.py, and optimizer.py.

The observations created now are a simple list of 10 values, which get added a random white noise by the obs operator.

Next challenge is to also bring in statevector.py from the baseclass as well, without dependencies on external files.

Updated the cartesius platform file to Python3

We changed the master project to once again run the random observation operator in python 3, using the gridded statevector and the ObsPack GlobalViewplus2 on capegrim. Next to do is to make this project also run without the specific parts but instead with baseclasses, and to program something that allows different templates on different machines.

The templates for jobs and rc-files used by start_ctdas.sh are now in a separate templates folder. This allows each user to modify their templates for running if needed, and to add templates for their own purpose.
