Add optional flags to disable SOA->legacy conversion and GPU->CPU tra…

…nsfer (#132)

Always produce the CPU cluster and rechit collections, since they are needed anyway.
Add transfer and conversion flags to clusterizer, rechits and CA.
Add a skeleton for the future pixel track producer.
Add customize functions to disable conversions to legacy formats, and to disable unnecessary GPU->CPU transfers.
