[PATCH v2 0/4] Introduce replica local spaces

[Vladimir Davydov]

This patch introduces a new space option, group_id, which defines how
a space is replicated. If it is 0 (default), the space is replicated
throughout the cluster. If it is 1, the space is not replicated.
For more information, see patch 4.

v1: https://www.freelists.org/post/tarantool-patches/PATCH-06-Introduce-replica-local-spaces

Changes in v2:
 - Use group_id space option instead of is_local flag, as this is more
   flexible and will allow us to implement fully-functional replication
   groups in future (Kostja).
 - Refactor code used for committing NOP requests (Kostja).
 - Rename space_opts::temporary to is_temporary (Kostja).
 - Add a comment to request_create_from_tuple (Kostja).
 - Remove merged patches from the patch set (patches 1-3 from v1).

Vladimir Davydov (4):
  txn: do not require space id for nop requests
  xrow: make NOP requests bodiless
  Rename space_opts::temporary to is_temporary
  Introduce replica local spaces
