Fix whitespace that occurs after comma

Use a custom tuple of separators for json.dumps that avoids
having the comma+space, which looks bad if this is ever committed.
Replace it by just having ": " and "," (no space after) instead.

An example of this so that it can be more clear:

Note the above paste where the old version has spaces after
commas where as the newer version does not have these spaces.

oslo.config-1.2.1 has a required fix for interaction
with argparse, which effects trove and glance at least.
