https://github.com/tarantool/tarantool/tree/sergepetrenko/gh-3428-replication-connect-quorum

Previously replication_connect_quorum setting was ignored during initial
bootstrap and during replication reconfiguration: the instance tried to
connect to every other instance listed in box.cfg.replication, and threw
an error, if it faild to do so. Now instance tries to connect to every
other instance possible during replication_connect_timeout, but doesn't
throw an error, if it was able to connect to replication_connect_quorum
instances.

First patch updates test-run to allow to pass arguments to instances
started with create_cluster.

Second patch utilizes the new functionality of test-run to update replication
tests with easy to control start options for instances.
Also alter on_replace.lua instance file to eliminate possible timing error, when
executing code before box.once could cause an error "user 'cluster' is not found".

Third patch introduces new replication_connect_quorum behaviour and adds
a test case to check that replication_conenct_quorum isn't ignored anymore.

Changes in v4: 
  - split the patch into 3 separate patches.
  - update test-run to allow passing start
    arguments to create_cluster().
  - update comments to match new behaviour.
  - in test instances when no timeout option
    is passed, set a default option.
  - be consistent when choosing timeouts
    for tests.

Changes in v3: 
 - Added a documentation request to TarantoolBot to
   commit message.
 - removed timeout parameter from box_sync_replication()
   and replicaset_connect()
 - rewritten replication tests to start instances with
   different replication_connect_timeout and 
   replication_timeout parameters. This made tests run 
   faster and more stable.
 - added a new test case to replication/quorum.test.lua
   to check that replication_connect_quorum isn't ignored
   anymore during bootstrap and reconfiguration.

Changes in v2: 
 - change test/replication/ddl.lua instance file to fix 
   test failure on Travis.

Serge Petrenko (3):
  test: update test-run
  Add arguments to replication test instances.
  replication: do not ignore replication_connect_quorum.
