[~sjlee0], Thanks for the detailed explanation now i am clear about the plans 
for TimelineClient and indirect support of flush for it.
bq. If these events are already associated with containers any way, they are 
not an issue, right?
Well [~djp] had pointed for 2 new stuff as part of this jira(apart from the 
existing container life cycle events), one was NM side application events and 
other was container resource localization events. In the later case again 
(similar to NM Side Application event) multiple resource paths can be localized 
for a given container, so different states of localization cannot be directly 
put as event ID's as we need to also publish the information of which resource 
this event belongs too.   
hence had suggested earlier as :
??For Localization i feel it can be under ContainerEntity and the EventID can 
localized resource.??
