Rollback for GRID support

[HealthyPear]

When I added protopipe.pipeline.utils.prod3b_array I made some changes that influenced the grid interface code. Since at the time the GRID support was put on hold, I didn't even think that it could be a problem. Indeed since the 2 repos are de facto separated, there was no automatic test to catch this...

The following changes have been rolled back now:

• removed the camera ID list argument in the general analysis configuration file because that function guesses the properties of the Prod3b array used automatically. I added back that argument the must be filled by the user. One can put also all the cameras, since protopipe.pipeline.utils.prod3b_array will take care of it anyway (making that argument a dummy one).
• same thing for the command line argument in write_dl1.py,
• energy estimation command line argument was set to boolean, now it's again a string (this I don't know why was changed actually)

Other changes: I also added a comment about using absolute paths when defining the simtel files lists to be used. This is useful since I plan to enable the use of a container and the paths could be different from my personal setup.

Note: we should check if something like protopipe.pipeline.utils.prod3b_array already exists in ctapipe for Prod3b, otherwise it would be wise to add it, at least for Prod5 (issue to be opened soon to be sure).
