* 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" }}

* 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.

Addresses: #3512
This adds a new counter metric `alertmanager_alerts_supressed_total`
that is incremented by `len(alerts)` when an alert is suppressed for
being outside of a time_interval, ie inside of a mute_time_intervals or
outside of an active_time_intervals.

* fix: broken notifier tests
- fixed metric count check to properly check the diff between
input/output notifications from the suppression to compare to suppression
metric, was previously inverted to compare to how many notifications it
suppressed.
- stopped using `Reset()` to compare collection counts between the
multiple stages that are executed in `TestMuteStageWithSilences()`.
the intent was to compare a clean metric collection after each stage
execution, but the final stage where all silences are lifted results in
no metric being created in the test, causing `prom_testutil.ToFloat64()`
to panic. changed to separate vars to check counts between each stage,
with care to consider prior counts.

This commit removes the metrics from the compat package
in favour of the existing logging and the additional tools
at hand, such as amtool, to validate Alertmanager configurations.
Due to the global nature of the compat package, a consequence
of config.Load, these metrics have proven to be less useful
in practice than expected, both in Alertmanager and other projects
such as Mimir.
There are a number of reasons for this:
1. Because the compat package is global, these metrics cannot be
reset each time config.Load is called, as in multi-tenant
projects like Mimir loading a config for one tenant would reset
the metrics for all tenants. This is also the reason the metrics
are counters and not gauges.
2. Since the metrics are counters, it is difficult to create
meaningful dashboards for Alertmanager as, unlike in Mimir,
configurations are not reloaded at fixed intervals, and as such,
operators cannot use rate to track configuration changes
over time.
In Alertmanager, there are much better tools available to validate
that an Alertmanager configuration is compatible with the UTF-8
parser, including both the existing logging from Alertmanager
server and amtool check-config.
In other projects like Mimir, we can track configurations for
individual tenants using log aggregation and storage systems
such as Loki. This gives operators far more information than
what is possible with the metrics, including the timestamp,
input and ID of tenant configurations that are incompatible
or have disagreement.

There is no need to register these metrics in amtool, so use
compat.NewMetrics(nil) instead of compat.RegisteredMetrics.
