Deprecated. ComponentManager and RoleManager are deprecated

Construct a new LifecycleHelper that can be used repeatedly to setup several components.

Note : if a parameter is null, the corresponding method isn't called (e.g. if configuration is null, configure() isn't called).

Parameters:

logger - the Logger to pass to LogEnableds, unless there is a LogKitManager and the configuration specifies a logger name.

context - the Context to pass to Contexutalizables.

componentManager - the component manager to pass to Composables.

roles - the RoleManager to pass to DefaultComponentSelectors.

configuration - the Configuration object to pass to new instances.
