Draft: e-tag dataset and parser tool

Miha Muskinja requested to merge mmuskinj/athena:master-ETagParser into master

Following the discussion in ATEAM-787 and core-sw meeting, I created a .csv dataset and a parsing tool for e-tags. The dataset is created from the PMG TWiki page: https://twiki.cern.ch/twiki/bin/view/AtlasProtected/PmgMcSoftware.

The tool return a map<string, string> object given an e-tag string with the information from the TWiki page. This can be coupled with the info from the in-file metadata to find out the specific version of the MC generator software (e.g. Sherpa version). The tool has both a python and a C++ interface.

Currently the tool has no clients, but in the future it can be used to update the in-file metadata e.g. at the start of derivation jobs. Example usage via CLI:
