Optimized NIC rule deletion
Rather than sending one REST delete command per rule
the server driver batches multiple rule IDs into a
single delete command.
Also performed some memory optimizations and refactoring.
Smarter batching to avoid exceeding the memory constraints of
webservers.
Lowered the rule deletion batch size due to the message:
"Your HTTP header was too big for the memory constraints of
this webserver".
Batch size for rule deletion has become a configurable
property.
