release-0.19.0

What's Changed

• Now 'clickhouse-operator' user is restricted to an IP address of the pod where clickhouse-operator is running. It can not be used from anywhere else.
• In addition to hostRegexp, 'default' user is restricted to IP addresses of pods of the CHI. This fixes connectivity issues between shards in GKE.
• ClickHouse 'interserver_http_host' is set to the service name and matches 'remote_servers'. It can be changed to full names with 'replicasUseFQDN' setting if needed. This fixes connectivity issues between replicas in GKE.
• Changed the way schema is propagated to new shards. It is currently controlled by two cluster level settings:

  schemaPolicy:
    replica: None | All (default)
    shard: None | All (default) | DistributedTablesOnly

Previously, when adding shards only distributed tables and dependent objects were created (DistributedTablesOnly).

• Added support for adding custom CA for operator connection to ClickHouse by @SuzyWangIBMer in #930
• Fixed support of '{uuid}' macro for Atomic databases. Closes #857
• Fixed a bug when replica sometimes was not removed from ZooKeeper when scaling down the cluster
