Fabian Reinartz 3269bc39e1 *: switch group key to matcher serialization
Turn the GroupKey into a string that is composed of the matchers if the
path in the routing tree and the grouping labels.
Only hash it at the very end to ensure we don't exceed size limits of
integration APIs.

This switches the nflog to generate Go code via gogoproto and thereby
use standard library timestamp types.

nflog: use alert set instead of hash for deduplication
Building a hash over an entire set of alerts causes problems, because
the hash differs, on any change, whereas we only want to send
notifications if the alert and it's state have changed. Therefore this
introduces a list of alerts that are active and a list of alerts that
are resolved. If the currently active alerts of a group are a subset of
the ones that have been notified about before then they are
deduplicated. The resolved notifications work the same way, with a
separate list of resolved notifications that have already been sent.

Fabian Reinartz 72fdf3d3ab *: integrate nflog
This commit replaces the previous NotifyInfo provider with the new
nflog package. It needs adjustments in the behavior of the deduping
stage.
The nflog stores notification digests per receiver per alert aggregation
group rather than one entry for alert per receiver. This drastically
reduces the number of entries and removes interference
across aggregation groups.

Fabian Reinartz 086d581cf8 nflog: add gc/snapshotting maintenance, remove delete
This removes the Delete function from the interface as the log
should be append-only and only be reduced by expired entries.
This also adds an argument to configure a background processing routine,
which periodically garbage collects and snapshots.

Fabian Reinartz 3d8e60ded7 nflog: add notification log package
This adds a new nflog package meant to replace provider.Notifies. It
has a central protobuf type package, which is also meant for usage for
other packages and the API.
The generated Go types are also the in-memory representation.
