SpaceCharge service configurations

[PetrilloAtWork]

So far ICARUS is getting away with claiming space charge is negligible and with a SpaceChargeService configuration that just disables the corrections (fcl/services/correctionservices_icarus.fcl).

Space charge seems to be very popular anyway. Enough so that a proliferation of boilerplate configuration is happening in our configuration files. It is time to centralise the possible configurations into a single configuration file (e.g. spacecharge_icarus.fcl) and provide there some precooked configuratins (icarus_nospacecharge, icarus_nominalspacecharge and whatever), and link one of them to the "standard" configuration.

I don't have the expertise on the subject to decide the content of these configurations and how many of them are needed. More expert people than me (esp. from the SBN world) would have to contribute.

@mrmooney @varanini assigning you to coordinate on this if that's ok, and make sure we have something consistent for SBND.

@marcodeltutto and Alessandro M., good to keep you looped in ...

[varanini]

@mrmooney is more of an SCE expert than me. But I would agree (maybe adding a double space charge configuration for testing could be a good idea). We should be careful about not correcting for SCE twice (there was a similar problem for SBND at the recent calib workshop)

[marcodeltutto]

Thanks @wesketchum. We can actually work on having the same (or similar) configurations in sbndcode in a spacecharge_sbnd.fcl.

Just to clarify @mrmooney and @varanini are we happy that the current Stage1 reconstruction does not apply SCE corrections to the tracks in ICARUS?

[varanini]

OK for me
