Refactor function parse_subscription_options. 

Instead of using multiple parameters in parse_subscription_options
function signature, use the struct SubOpts that encapsulate all the
subscription options and their values. It will be useful for future work
where we need to add other options in the subscription. Also, use bitmaps
to pass the supported and retrieve the specified options much like the way
it is done in the commit a3dc926009.
