Sergey Uttsel updated IGNITE-20058:
-----------------------------------
Description:
*{{Motivation}}*
{{DistributionZoneManagerAlterFilterTest.testAlterFilter}} is flaky and with
very low failure rate it fails with NPE (1 fail in 1500 runs)
{noformat}

*Implementation Notes*
The reason is the wrong start order of the components:
# Firstly metastorage watch listeners are deployed.
# Then DistributionZoneManager is started.
So I change this order to fix the issue.
Also I will close https://issues.apache.org/jira/browse/IGNITE-19403 when this
ticket will be closed.
