[SYSTEMDS-2634] Reduced number of RPCs calls in federated backend

This patch improves the performance of the federated runtime backend by
merging the execution and cleanup RPC request batches into a single
batch of requests. Since every batch returns only a single response, we
now carefully select the right get_var, error, or other responses to
return. Overall, this reduced the number of RPC calls by almost 2x and
removed unnecessary synchronization barriers.
