4acad5795b Expose the status of transaction within Raft 
Summary:
For proper client interaction, we need to expose the (term_id, log_index)
pair for the transaction that's about to be replicated and we need to be able
to retrieve the status of a transaction defined by that pair. Transaction
status can be one of the following:

  1) REPLICATED (self-explanatory)
  2) WAITING (waiting for replication)
  3) ABORTED (self-explanatory)
  4) INVALID (received request with either invalid term_id or invalid log_index)

Config: 100msPeriodicGc, Time: 30.7956

It is not that bad if there is a core dedicated to doing garbage collection.

Summary:
This is a preparation step in case we want to have a custom allocator in

Introduction of MemoryResource and removal of `calloc` has reduced the
performance a bit according to micro benchmarks. This performance hit is
not visible on benchmarks which do more concurrent operations.
