Distinguish events between block allocation request and reload request

[Xianqing Yu]

Hi VCL developers:

I am trying to enable block allocation in CCMP module. CCMP module is the 
new module we make VCL work with IBM Cloud. In order to make the block 
allocation work, I have to distinguish block allocation request from normal 
reload request (the request send by VCL when one user end one reservation). 
I wonder is there any parameters in database or somewhere else can help me 
to distinguish these two events?

Thanks,

Xianqing
