prometheus/rules
Julius Volz 0e48c18bbf Allow omitting the metric name in queries.
This allows the following expression syntaxes for selecting timeseries:

  foo                    (already valid before)
  foo{}                  (already valid before)
  {job="prometheus"}     (new, select all timeseries for job "prometheus")

Omitting both the metric name *and* any label matchers ("" or "{}") will
still yield a syntax error.

To get all timeseries, you could do:

    {__name__=~".*"}
       or, without relying on knowledge about __metric__:
    {job=~".*"}
