// WL#11465 AdminAPI: AdminAPI: change cluster member options
//
// Currently, it's not possible to change a previously configuration option
// of a running Cluster or Cluster active member in the AdminAPI.
// Such settings can be set during the calls to:
//
//     - dba.createCluster()
//     - <Cluster.>addInstance()
//     - <Cluster.>rejoinInstance()
//
// In order to support changing configuration options of cluster members
// individually or globally, the AdminAPI was extended with two new commands:
//
//     - <Cluster.>setOption(option, value)
//     - <Cluster.>setInstanceOption(instance, option, value)
//
// Each command has a defined set of accepted options supported by the AdminAPI.
//
// On top of that, in order to verify which are the cluster configuration options
// in place, a new command was added to the AdminAPI:
//
//     - <Cluster.>options([options])
