This corresponds to NEO/py commit ef5fc508 (Make the number of replicas modifiable when the cluster is running). One important change in the protocol is that Client no longer queries Master for partition table - instead M pushed partTab to C right after identification (after pushing nodeTab).

NEO 1.12 * tag 'v1.12': (28 commits) Release version 1.12 master: reject drop/tweak ctl commands that could lead to unwanted status qa: extend test reproducing the migration of a big ZODB to NEO neoctl: better display of full partition tables Bump protocol version tweak: add option to simulate tweak: do not crash when trying to remove all nodes tweak: do not touch cells of nodes that are intended to be dropped Better error reporting from the master to neoctl for denied requests Make 'neoctl print pt' report the number of replicas Make the number of replicas modifiable when the cluster is running New --new-nid storage option for fast cloning qa: fix 2 tests with ZODB5 qa: new tools/stress options to evaluate MySQL engines qa: provide a way to let tests start 1 mysqld per storage node mysql: make 'user' actually optional in the DB connection string mysql: specify column families for RocksDB qa: add testIncremental (testImporter) test importer: fix hidden "maximum recursion depth exceeded" at startup importer: fix closure of ZODB, and also do it when the import is finished sqlite: fix resumption of migration to NEO with Importer qa: fix a random failure in threaded tests importer: speed up startup when the import is already finished importer: fix replication (as source) once import is finished storage: fix DatabaseManager.getLastTID with max_tid qa: remove 2 useless unit tests storage: allow the master to change our node id Rename --uuid command-line options into --nid importer: fix possible data loss on writeback

After NEO/py commit 9f1e4eef (Use argparse instead of optparse) neomigrate signature changed: * -s and -d were removed: src and dst are specified as just arguments; * -q was added to silence importer-related warnings.
