beorn7 14730c70c0 promhttp: Bite the bullet and implement all 32 possible interface combos
As it turned out, it's not that esay to guess "common" combination of
interface upgrades. So I decided to just implement all 32 possible
combination of interface upgrades. (Only 16 with Go 1.7 and earlier.)

Clearly, this calls for code generation. But right now, we still need
to find out what's the best form of the code. For later additions,
implementing code generation might be useful.

Note that newDelegator is called for each HTTP request. Thus, this
commit aims to make the upgrade selection quick. (After the type
checks, it's just directly accessing an element in a slice.)

beorn7 753a259e20 Improve promhttp tests
- Use local registry to avoid conflicts between tests.
- Expose https://github.com/prometheus/client_golang/issues/299 by
  using ConstLabels in a test.
- Improve example: Buckets and help string must be consistent, even
  if the former is not enforced as of now, but see
  https://github.com/prometheus/client_golang/issues/222

api: creates versioned package for prometheus v1 api
This commit creates a new package to hold the prometheus
v1 API interface. This interface will contain all the funcionality
exposed by Prometheus v1 HTTP API.

The underlying http client is kept on the api package since it
may be reused across diferent API versions and also by the Alertmanager
api package (to come.)

Tobias Schmidt ae77d82d88 Fix invalid Timer (gauge) example
The example method is assumed to be used as main() function. As a main()
function doesn't have any return values, the example doesn't compile and
is invalid.

beorn7 9c4b7780d7 Allow Summaries with empty objectives and deprecate DefObjectives
This also updates all tests and examples to use explicitly set
objectives.

In v0.10, DefObjectives will be completely removed, and the default
Summary will have no objectives then.

Fixes #118

beorn7 6bff9dc5a4 Make heap_released_bytes a Gauge.
It's not a counter after all.

Also, remove a misleading part of the sys_bytes help string.

beorn7 89ca0458cb Change the Timer API
This finally makes the (presumably) common simple case as simple as it
gets.

The still quite common (but less common) case of using a Gauge is
slightly more verbose now, but not needing to provide a separate
constructor is totally worth it.

Finally, the advanced use case is not really more verbose as in my
original suggestion. However, the logic to decide which Observer to
use is now all in the ObserverFunc handed in at construction
time. This is deliberate and desired. It makes sure the selection
mechanism is all spelled out there. No surprises buried deep in the
function code somewhere.
