Fix CP3SlurmUtils issues; various other changes

This mainly solves the non-ideal situation with the CP3SlurmUtils package. After this is merged you'll have to:

• upgrade bamboo
• install CP3SlurmUtils using python -m pip install -i https://test.pypi.org/simple/ CP3SlurmUtils (inside of your bamboo venv)
• remove the part in your PYTHONPATH pointing to my or Kyle's CP3SlurmUtils folder
• do mkdir ~/.config/CP3SlurmUtils; ln -s (abs path to)/ttbbRun2Bamboo/config/defaults.cfg ~/.config/CP3SlurmUtils

Also, you can do the following to avoid having to specify the .ini file each time you call bambooRun: ln -s (abs path to)/ttbbRun2Bamboo/config/bamboo.ini ~/.config/bamboorc

Other changes include (mainly):

• Remove duplicate application of b-tag SF patches in the controlPlotter. Instead, there is now a command-line argument to select which ones to use.
• Better handle the case when we run on both the 4FS and 5FS samples (note: for now the samples_template.yml was changed to make sure the ttB part is only taken from the 4FS samples): the overlap is removed before running plotIt (in the controlPlotter only for now!!)
• With topNanoAOD the branch storing the PS weights has changed
• QCD (renormalization/factorization scales): instead of taking the envelope of the 7-point variation, create two separate uncertainties for muR/muF. Further checks might be needed to compare with the simultaneous variation of muR and muF.
• Added a script to check the PS or QCD weights in nanoAOD files, and thus:
• I've updated the list of samples with buggy PS or QCD weights in /t3home/swertz/bambooDev/ttbbRun2Bamboo/config/buggyThSyst.yml. It's also possible some remaining issues in the QCD weights (order of weights different from assumed one) remain: TODO.

Feedback welcome!
