Complete fix for HcalCalPedestal AlCaReco (76X)

[diguida]

This is needed to make the HCalCalPedestal producer run in the AlCaReco matrix for data.
It is a forward port of #10507

• diguida@de26bf5 is partially included by diguida@f62a905 only for the cleanup of Configuration/StandardSequences/python/AlCaRecoStream_Specials_cff.py for multiple inclusions of AlcaReco DQM instances;
• diguida@7794908 has been already forward ported;
• diguida@c46f1ea featuring the cleanup of the HcalCalPedestal AlCaReco sequence is cherry-picked.
• diguida@809cbb9 featuring a fix of the module names in the AlCaReco and the selection of the correct output collections is cherry-picked;
• diguida@f4b69df adding a test cfg is cherry-picked.
