Add Open Compute Project log page (when available) to stats gathered on NVMe devices.

[sbates130272]

It would be desirable to have the nvme collector(s) gather information from the OCP stats log page as well as from the smart-log page. Note this has been discussed in the nvme-cli project. I am happy to work up a PR for this.

One question I have is if this needs to be done for the python and the shell script? Is the shell script being depreciated?

[dswarbrick]

Yes, the shell script will be deprecated.

@sbates130272 You might want to hold off submitting any PR just yet, as it seems we will have to do some non-trivial refactoring of the collector. See #226.

Thanks @dswarbrick. I will keep a track of #226 and see how things play out.
