Limit number of revert tombstone SSYNC requests
Revert tombstone only parts try to talk to all primary nodes - this fixes it to randomize selection within part_nodes. Corresponding probe test is modified to reflect this change. The primary improvement of this patch is the reconstuctor at a handoff node is being able to delete local tombstones when it succeeds to sync to less than all primary nodes. (Before this patch, it requires all nodes are responsible for the REVERT requests) The number of primary nodes to communicate with the reconstructor can be in dicsussion more but, right now with this patch, it's (replicas - k + 1) that is able to prevent stale read. *BONUS* - Fix mis-testsetting (was setting less replicas than ec_k + ec_m) for reconstructor ring in the unit test Co-Authored-By: Kota Tsuyuzaki <tsuyuzaki.kota@lab.ntt.co.jp> Co-Authored-By: Clay Gerrard <clay.gerrard@gmail.com> Change-Id: I05ce8fe75f1c4a7971cc8995b003df818b69b3c1 Closes-Bug: #1668857
