Add systematics regex support to SysListLoaderAlg

I'm not sure why we did not have this before, but it would be nice to have a central location to filter the systematics one really wants to use.

/cc @krumnack

This merge request affects 1 package:

• PhysicsAnalysis/Algorithms/AsgAnalysisAlgorithms

Adding @krumnack ,@tadej as watchers

Since I'm not entirely sure, please also comment on the warnings on this one.--L1

You can look in the CI monitor where you see that warnings come from ElectronPhotonSelectorTools (https://bigpanda.cern.ch/compsview/?nightly=MR-CI-builds&rel=MR-27490-2019-10-25-12-51&ar=x86_64-centos7-gcc8-opt).

Thank you. I wasn't sure so I ask just in case. Approved!--L1
