/**
 * Defines service configuration properties.
 *   name:
 *     The name of the config property that is understood by Ambari server and agent.
 *     E.g., "datanode_du_reserved"
 *
 *   displayName:
 *     The human-friendly display name of the config property.
 *     E.g., "Reserved space for HDFS"
 *
 *   description:
 *     The description of the config property.
 *     E.g., "Reserved space in GB per volume"
 *
 *   defaultValue:
 *     The default value of the config property.
 *     E.g., "1"
 *
 *   isReconfigurable:
 *     Whether the config property can be reconfigured after it has been initially set and deployed.
 *     If this is unspecified, true is assumed.
 *     E.g., true, false
 *
 *   isOverridable:
 *     Whether the config property can be overridden by hosts.
 *     If this is unspecified, true is assumed.
 *
 *   isRequired:
 *     Whether the config property is required or not.
 *     If this is unspecified, true is assumed.
 *     E.g., true, false
 *
 *   displayType:
 *     How the config property is to be rendered for user input.
 *     If this is left unspecified, "string" is assumed
 *     E.g., "string", "int", "float", "checkbox", "directories", "custom", "email", "masterHost", "slaveHosts"
 *
 *   unit
 *     The unit for the config property.
 *     E.g., "ms", "MB", "bytes"
 *
 *   isRequiredByAgent:
 *     Whether the config property is required by agent or not.
 *     If value is false then it will be not persisted in global configuration
 *
 *   serviceName:
 *     The service that the config property belongs to.
 *     E.g., "HDFS", "MAPREDUCE", "ZOOKEEPER", etc.
 *
 *   category: the category that the config property belongs to (used for grouping config properties in the UI).
 *     if unspecified, "General" is assumed.
 *     E.g., "General", "Advanced", "NameNode", "DataNode"
 *
 *   index: the sequence number in category, that point to place where config located regarding all rest in category.
 *     if unspecified, push to the end of array.
 *     E.g., 0, 1, '2'
