Update UL 17 ingredients

[edjtscott]

This PR designed to include the required updates for the UL 17 dataset. So far just updates the photon systematics file in the MetaConditions (previously not set to the legacy version) and adds the databases needed for the JEC and JER (not yet included in any global tag).

Expect additional commits from @rchatter but these two aspects should be the most important ones for anyone hoping to run ntuples asap.

@edjtscott are you sure that the JEC and JER are not available through Frontier and only through the sqlite file?

[edjtscott]

In the tables here it says the GT with these corrections is tba, which is why I added them by hand

[edjtscott]

@simonepigazzini I now tried reverting to frontier, as we discussed. It seems that the JEC are there but not the JER; I'm currently getting an error Tag "JR_Summer19UL17_JRV2_MC_PtResolution_AK4PFchs" has not been found in the database.

So if OK with you I will leave it as-is for now?

[simonepigazzini]

Ok fine. I will blame JME for sinking my masterplane of reading everything from db

hi all (@simonepigazzini @youyingli @zhangyu0217), this PR should now be complete from our side. Could you double check it all looks sensible before merging? Thanks a lot
