/**
 * Sharding configuration
 * @param numberOfShards number of shards (see documentation on how to choose this), should be same on all nodes
 * @param selfHost hostname or IP address of the current pod
 * @param shardingPort port used for pods to communicate together
 * @param shardManagerUri url of the Shard Manager GraphQL API
 * @param serverVersion version of the current pod
 * @param entityMaxIdleTime time of inactivity (without receiving any message) after which an entity will be interrupted
 * @param entityTerminationTimeout time we give to an entity to handle the termination message before interrupting it
 * @param sendTimeout timeout when calling sendMessage
 * @param refreshAssignmentsRetryInterval retry interval in case of failure getting shard assignments from storage
 * @param unhealthyPodReportInterval interval to report unhealthy pods to the Shard Manager (this exists to prevent calling the Shard Manager for each failed message)
 * @param simulateRemotePods disable optimizations when sending a message to an entity hosted on the local shards (this will force serialization of all messages)
