sandesh client code needs to move to use size based watermarks

[Megh Bhatt]

Recently size based water mark support was added in WorkQueue but looks like the sandesh c++ client code is still using message count based water marks. Its better to move it to size based water marks

This fix changes the sandesh send queue size based on
the actual message size upon enque/dequeue.

Compiler:
---------
Sandesh compiler is changed to generate GetSize()
which returns the size of the sandesh

Library:
-------
Introducing a new structure Element which consists of the
sandesh and GetSize function to return size of sandesh

Change the sandesh_queue_.Enqueue and Dequeue to take
Element as argument and not sandesh

Test if Sandesh GetSize function returns value properly.
Test if sandesh queue size changes
by the message size upon enqueue/dequeue
