name - the name of the enum constant to be returned.
IllegalArgumentException - if this enum type has no constant
with the specified name
NullPointerException - if the argument is null
public void initHaEnvironment(String clusterName,

It is primarily used by a container to inject the proper cluster name and
instance name values that are later used to initialize all BackingStoreConfiguration
instances created via initBackingStoreConfiguration(String, Class, Class)
