We have a bit of a mess with globals in the sharp daemon. Let's start formalizing it a bit. Future commits will take advantage of this, as that we need to have the ability to start dumping stats about commands we have issued. These changes will be useful for debugging and understanding what is going on. Signed-off-by: Donald sharp <sharpd@cumulusnetworks.com>
