Added an "m=metric{tagk1=tagv1,...}" style query parameter to the
/api/uid/tsmeta endpoint. Allows for retrieving the TSMeta of a time series
without knowing the TSUID, only be specifying the timeseries using the
metric and tags.
Enabled creation of TSMeta objects via POST by metric and tags. Needs to be
enabled explicitly by create=true flag in the URL. If specified creates
both a TSMeta object and initializes the counter.
