beorn7 c06fb788be Relax consistency checks during gathering 
Also, clarify in the doc comment.

Previously, the assumption was that inconsistent label dimensions are
violating the exposition format spec. However, especially with the
knowledge that OpenMetrics will explicitly allow inconsistent label
dimensions in expositions, we should allow it in client_golang, too.

Note that registration with proper Descs provided will still check for
consistont label dimensions. However, you can "cheat" with custom
Collectors as you can collect metrics that don't follew the provided
Desc (this will be made more explicit and less cheaty once #47 is
fixed). You can also create expositions with inconsistent label
dimensions by merging Gatherers with the Gatherers slice type. (The
latter is used in the Pushgateway.)

Effectively, normal direct instrumentation will always have consistent
label dimensions in this way, but you can cover special use cases with
custom collectors or merging of different Gatherers.

Bryan Boreham 8fbbc9bc6b Decode JSON body when Prometheus returns 400 to an api call 
400 and 422 are documented error codes from Prometheus, so we should
attempt to parse the error returned for both of them.

Needed to change a test that was requiring the old behaviour - made it
use 500 instead of 400.

beorn7 1b56b5c497 Be more robust about nil pointers in protobuf 
While not strictly correct, it can easily happen that proto messages
are created that use nil pointers instead of pointers in empty strings
to denote an empty string.
