CPAlgorithms: user-side improvements to the config blocks
The following changes are made to the config blocks:
- make the MC campaign metadata accessible to the ConfigAccumulator --> allows to automatically configure the PRW
- the PRW config block that was set up by the ConfigText is only the example one used in the CI --> rename it to "test" and set up the correct (autoconfig) PRW for actual users
- add functions to extract the FTAG and JES MC/MC metadata information from flags, and make it accessible to the ConfigAccumulator --> allows to automatically configure the FTAG MC/MC parameter
generator
(unique text config instead, instead of 1 per generator) - remove the default variable
jet_m
for small-R jets --> move it to large-R jets instead
