Component may use this function to stop doing work before the stop of the components that depend on it.
Base components may override it and make final
to do some work before the derived object constructor is called. Don't use it otherwise.
Reimplemented from components::RawComponentBase.
Reimplemented in urabbitmq::ConsumerComponentBase, and components::Server.

Component may use this function to finalize registration of other components that depend on it (for example, handler components register in server component, and the latter uses OnAllComponentsLoaded() to start processing requests).
Base components may override it and make final
to do some work after the derived object constructor is called. Don't use it otherwise.
Reimplemented from components::RawComponentBase.
Reimplemented in urabbitmq::ConsumerComponentBase, components::Server, and server::handlers::Ping.

Called once if the creation of any other component failed. If the current component expects some other component to take any action with the current component, this call is a signal that such action may never happen due to components loading was cancelled. Application components might not want to override it.
