[SYSTEMDS-2784] Enable lineage-based reuse in federated workers

This patch builds the initial infrastructure for lineage based
reuse in federated workers. Changes include:
 - Lineage tracing InitFEDInstruction
 - Lineage trace READ and PUT requests. For PUT, lineageitem hash
   is sent with the request, which will be replaced by Adler32
   in future commits.
 - Disable compiler assisted optimizations for lineage-based reuse
   (e.g. mark for caching) for the workers.
 - Testing infrastructure.
