* API: Make conversion functions public
All types are public so it makes sense to make these functions also
public for ease of downstream consumption.

A Peer as defined by the `cluster` package represents the node in the
cluster. It is used in other packages to know the status of all of the
members or how long should we wait to know if a notification has already fired.
In Cortex, we'd like to implement a slightly different way of
clustering (using gRPC for communication and a
hash ring for node discovery).
This is a small change to support that by changing the consumer of other
packages to an interface.
Silences and Notification channels don't need an interface as they take
a `func([]byte) error` as a parameter.

* Make filter labels consistent with Prometheus
Filtering the alert out when the label is missing precludes a
possible match for an empty value. This change allows the
match to be evaluated.

* api/v2: add path and method to API v2 logs
When an API v2 handler logged a message, the log wouldn't include the
path and method. Since different handlers perform the same validations
(e.g. matchers for alerts and silences), it isn't easy to know which
handler was invoked (though the logged filename
+ line number provides a hint).

* api/v2: sort silences similarly to v1 api
Sort the queried silences to match behaviour in the v1 api.
Sort silences in-place instead of creating multiple slices.
Use separate function for sorting silences for easier testing.
Add unit test for sort order.

Add version tracking of silences states. Adding a silence to the state
increments the version. If the version hasn't changed since the last
time an alert was checked for being silenced, we only have to verify
that the relevant silences are still active rather than checking the
alert against all silences.

This encapsulates the logic of querying and marking silenced
alerts. It removes the code duplication flagged earlier.
I removed the error returned by the setAlertStatus function as we were
only logging it, and that's already done anyway when the error is
received from the `silence.Query` call (now in the `Mutes` method).

Instead of handling all config specific logic inside
Alertmangaer.main(), this patch introduces the config coordinator
component.
Tasks of the config coordinator:
- Load and parse configuration
- Notify subscribers on configuration changes
- Register and manage configuration specific metrics

Most importantly, `api.New` now takes an `Options` struct as an
argument, which allows some other things done here as well:
- Timout and concurrency limit are now in the options, streamlining
the registration and the implementation of the limiting middleware.
- A local registry is used for metrics, and the metrics used so far
inside any of the api packages are using it now.
The 'in flight' metric now contains the 'get' as a method label. I
have also added a TODO to instrument other methods in the same way
(otherwise, the label doesn't reall make sense, semantically). I have
also added an explicit error counter for requests rejected because of
the concurrency limit. (They also show up as 503s in the generic HTTP
instrumentation (or they would, if v2 were instrumented, too), but
those 503s might have a number of reasons, while users might want to
alert on concurrency limit problems explicitly).

While the newly added in-flight instrumentation works for all GET
requests, the existing HTTP instrumentation omits api/v2 calls. This
commit adds a TODO note about that.

The context is created by the http.TimeoutHandler we use to set the
timeout.
I believe this is the only endpoint where propagating the timeout is
feasible and needed.
