Move pybatsim to Batsim 2.0 api

Merge changes made in the process of creating the Bebida scheduler and in parallel move to Batsim 2.0 api.

Basically, I made this merge request for you @lackner to see all the changes I have made. Here is a list of the main changes that may have an impact on your code: In batsim.py:

• Add a logger instead of prints
• Use Procset (which is fast and tested) instead of home made intervals
• Manage resources as a dict instead of a list
• JobKilled do not call jobComplete anymore (because batsim now send the killed jobs in JobComplete

In launcher I changed some default parameters for my convenience but we can argue on that :)

For the rest:

• Debug resources: resource 0 was excluded (if my_variable is a bad practice, specify is None make it non ambiguous)
• Debug jobs: job complete was called on all jobs instead of the completed jobs
• Add profile and parameters to fit to Batsim 2.0 new API
