If the original EndsAt is left in place, then as time moves forwards
past the EndsAt then firing alerts will be rendered and treated as
resolved alerts which can cause confusion and races. This is most
likely to happen on retries for a notification.

To aggregate by all possible labels use '...' as the sole label name.
This effectively disables aggregation entirely, passing through all
alerts as-is. This is unlikely to be what you want, unless you have
a very low alert volume or your upstream notification system performs
its own grouping. Example: group_by: [...]

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.
* Vendor dependencies.
This updates several old dependencies, removes
some that are no longer needed, and adds
`pkg/labels` from prometheus `dev-2.0` branch.
* Add metrics selector parsing code
This is a temporary simplified re-implementation
of promQL's metric selector parsing.
* Add alerts filtering
Filter alerts through `?filter=` query string.
* Add silences filtering
Filter silences through `?filter=` query string.
* Move `parse` to `pkg/parse`
This string value is initially used to store a receiver name. It is
later overloaded with a unique string identifier of <name, integration,
index>.
This renaming is in preparation to separate the two and use the Receiver
object of the nflogpb package.
