[FEATURE] Leverage coreRef for http reference in event analytics

[mengweieric]

Is your feature request related to a problem?
There are legacy usages of http in event analytics where core.http is passed in as props to some of the components in event explorer modules which is not a good practice as http may not be a necessary props for that component functionality wise.

What solution would you like?
Use coreRef/ or pass in component that directly depends on http instead
