Change subject: [catalog_manager] introduce --min_num_replicas flag ...................................................................... [catalog_manager] introduce --min_num_replicas flag This patch introduces a flag for Kudu master to enforce the minimum number of replicas for newly created tables in a Kudu cluster. Unless overridden, --min_num_replicas is set to 1 by default. For example, setting --min_num_replicas=3 enforces every new table to have at least 3 replicas for each of its tablets, so there cannot be a data loss when a single tablet server fails irrecoverably. I also added validators for the related flags to keep things more consistent and report misconfiguration errors as early as possible. This patch also contains a few test scenarios to cover the newly introduced functionality.
