simplify flat mixing configuration

[vlimant]

PR description:

When defining a flat mixing that is not in the release, one has to use the --customise_command .
With this PR it becomes simpler, just by adding --pileup 'Flat_10_50_25ns,{"Flat":[0,120]}' instead of

--pileup Flat_10_50_25ns --customise_commands "process.mix.input.nbPileupEvents.probFunctionVariable = cms.vint32(0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120) \n process.mix.input.nbPileupEvents.probValue = cms.vdouble(0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446,0.00826446)"
