Hi Imesh,

Great thought. This will considerably speed up instance activation process.

Shall we call the topic as 'initializer' to be generic? We can further
extend this to Application hierarchy model initialization and tenant model
initialization using the same topic. These are also published periodically
by AS and SM respectively.

Thanks.
