Just to be clear, this is different than the above because here we
are
talking about spaces in the tag NAMES.
So, as of right now, the Go client cannot support tag names OR values with
spaces in them. That's going to be a limitation we need to document, unless
we fix these two issues.
Sorry - I misspoke. It is more than spaces in tag names, the problem is when spaces are in
METRIC IDs. I suspect spaces in tag names will also fail, but for sure, spaces in METRIC
IDs cause the failure.
