Automatically configuring for Analysis Productions

When submitting Run 1 and Run 2 Analysis Productions most people take advantage of the automatically_configure: true option. This removes the need for people to handle information relating to input data and makes people's options files much more consise. It works by generating a Python file like this one which is prepended to the list of options files provided by the user:

from Configurables import DaVinci
try:
    DaVinci().Turbo = False
except AttributeError:
    # Older DaVinci versions don't support Turbo at all
    pass
DaVinci().RootInTES = '/Event/Bhadron'

DaVinci().InputType = 'MDST'
DaVinci().DataType = '2015'
DaVinci().Simulation = False
DaVinci().Lumi = True
from Configurables import CondDB
CondDB(LatestGlobalTagByDataType=DaVinci().DataType)

from Configurables import DaVinci
try:
    DaVinci().Turbo = False
except AttributeError:
    # Older DaVinci versions don't support Turbo at all
    pass
DaVinci().RootInTES = '/Event/AllStreams'

DaVinci().InputType = 'MDST'
DaVinci().DataType = '2018'
DaVinci().Simulation = True
DaVinci().Lumi = False
DaVinci().DDDBtag = 'dddb-20170721-3'
DaVinci().CondDBtag = 'sim-20190430-vc-mu100'

For Run 3 this option hasn't yet been implemented as it wasn't clear what should be done however we're now approching a state where it might start to be reasonable.

The mechanism for doing this in Run 3 was designed into lbexec and the extra_options parameter that people have been using when submitting productions. For example:

      extra_options:
        input_type: ROOT
        input_process: "TurboPass"
        input_stream: "bandq"
        input_raw_format: 0.5
        simulation: False
        data_type: "Upgrade"
        geometry_version: trunk
        conditions_version: master

I'm opening this issue to start the discussion around what we need to implement to be able to make this work robustly for 2024.

In general I think we should favour setting the defaults in the physics application itself if we can (possibly via the new FSRs).
