* Fix race condition in dispatch.go
This commit fixes a race condition in dispatch.go that would cause
a firing alert to be deleted from the aggregation group when instead
it should have been flushed.
The root cause is a race condition that can occur when dispatch.go
deletes resolved alerts from the aggregation group following a
successful notification. If a firing alert with the same
fingerprint is added back to the aggregation group at the same time
then the firing alert can be deleted.

* Bump prometheus/common to v0.52.3
This commit bumps prometheus/common to v0.52.3. It has a breaking
change where the metric alertmanager_build_info has been renamed
to go_build_info as the metric has been moved from prometheus/common
to prometheus/client_golang and the namspace argument has been
removed.

* Add GroupMarker interface
This commit adds a new GroupMarker interface that marks the status
of groups. For example, whether an alert is muted because or one
or more active or mute time intervals.
It renames the existing Marker interface to AlertMarker to avoid
confusion.

The elm npm package doesn't support linux/arm64. The easiest option

* Add date and tz functions to templates
This commit adds the date and tz functions to templates. This means
users can now format time in a specified format and also change
the timezone to their specific locale.
An example of how these functions work, and can be composed together,
can be seen here:
{{ .StartsAt | tz "Europe/Paris" | date "15:04:05 MST" }}

* Update TestRouteID tests

* Fix Route.ID() returns conflicting IDs
This commit fixes a bug where Route.ID() returns conflicting IDs.
For example, the configuration:
receiver: test
routes:
- matchers:
- foo=bar
continue: true
routes:
- matchers:
- bar=baz
- matchers:
- foo=bar
continue: true
routes:
- matchers:
- bar=baz
Gives the following Route IDs:
{}
{}/{foo="bar"}/0
{}/{foo="bar"}/{bar="baz"}/0
{}/{foo="bar"}/1
{}/{foo="bar"}/{bar="baz"}/0
When it should give these Route IDs:
{}
{}/{foo="bar"}/0
{}/{foo="bar"}/0/{bar="baz"}/0
{}/{foo="bar"}/1
{}/{foo="bar"}/1/{bar="baz"}/0

This commit rewrites the existing TestTimeActiveStage unit tests
to have complete isolation between test cases. Before this change,
each test case affected the state of its subsequent tests.
The motivation behind this change is to make it easier to assert
that alerts have been marked as muted.
