Adding possibility to get the Reconstruction parameters from OCDB (Marian)

Adding possibility to get the Reconstruction parameters from OCDB (Marian)

Just temporary fix

  The reconstruction parameters are used in the AliTPCclustererMI and AliTPCtrackerMI

  They are retrieved:
  0. User speciefied it in reconstruction macro
  1. if (not 0) from OCDB  - AliTPCcalibDB::GetRecoParam(eventtype)
  2. if (not 0 or 1) default parameter - High flux enevironment used

  FIXME:
  In the future  reconstruction parameters should be changed on event basis
  But for the moment, event types are still not defined
