nuodb_thread collection has issues relative to tag vs. field

[butson]

The goal here was to create a series per thread so that you could monitor cpu usage per thread. But the fields marked as tags don't necessarily allow this.

threadid is not a tag (probably should be)
state is a tag (probably should not be)

The reason threadid is not a tag is because of a limit I ran into at Temenos where you are limited to 1M series. I don't if/when this would be a problem in a normal deployment.

What I'm seeing on dashboard is that I can't create a series per thread which is what is desired.
