a913d0891c nixos/prometheus: filter out empty srcape_configs attributes 
This results in a smaller prometheus.yml config file.

It also allows us to use the same options for both prometheus-1 and
prometheus-2 since the new options for prometheus-2 default to null
and will be filtered out if they are not set.

739bdff4a4 nixos/prometheus/alertmanager: use ExecStart instead of script 
This results in a simpler service unit which doesn't first have to
start a shell:

  > cat /nix/store/s95nsr8zbkblklanqpkiap49mkwbaq45-unit-alertmanager.service/alertmanager.service
  ...
  ExecStart=/nix/store/4g784lwcy7kp69hg0z2hfwkhjp2914lr-alertmanager-0.16.2-bin/bin/alertmanager \
    --config.file /nix/store/p2c7fyi2jkkwq04z2flk84q4wyj2ggry-checked-config \
    --web.listen-address [::1]:9093 \
    --log.level warn

c95179b52f nixos/prometheus: add back the option services.prometheus.dataDir 
This is to ensure more backwards compatibility. Note this is not 100%
backwards compatible because we now require dataDir to begin with /var/lib/.

nixos/prometheus: get rid of empty arguments 
Previously the prometheus.service file looked like:

  ExecStart=/nix/store/wjkhfw3xgkmavz1akkqir99w4lbqhak7-prometheus-1.8.2-bin/bin/prometheus -storage.local.path=/var/lib/prometheus/metrics \
    -config.file=/nix/store/zsnvzw51mk3n1cxjd0351bj39k1j6j27-prometheus.yml-check-config-checked \
    -web.listen-address=0.0.0.0:9090 \
    -alertmanager.notification-queue-capacity=10000 \
    -alertmanager.timeout=10s \
     \

  Restart=always

Now it's:

  ExecStart=/nix/store/wjkhfw3xgkmavz1akkqir99w4lbqhak7-prometheus-1.8.2-bin/bin/prometheus \
    -storage.local.path=/var/lib/prometheus/metrics \
    -config.file=/nix/store/zsnvzw51mk3n1cxjd0351bj39k1j6j27-prometheus.yml-check-config-checked \
    -web.listen-address=0.0.0.0:9090 \
    -alertmanager.notification-queue-capacity=10000 \
    -alertmanager.timeout=10s
  Restart=always

Add prometheus2 configuration to the prometheus modules 
As the configuration for the exporters and alertmanager is unchanged
between the two major versions this patch tries to minimize
duplication while at the same time as there's no upgrade path from 1.x
to 2.x, it allows running the two services in parallel. See also #56037

c53703a6b2 nixos/prometheus: use append instead of insert for opening firewalls (#55224) 
Inserting with `-I` causes the rules to placed before `ctstate`
tracking, while `-A` places them alongside all other allow rules.

nixos/prometheus-dovecot-exporter: enhance socketPath documentation 
In Dovecot 2.3[1] the stats module changed and now the UNIX socket
provided by Dovecot by default isn't compatible anymore with the
exporter[2]. By enabling the `old-stats` plugin in Dovecot this issue
can be solved which should be documented in this module.

nixos/prometheus: make source_labels optional 
It's possible to skip `source_labels` entirely, an example for this is
the blackbox exporter configuration:

3873f43fc3 prometheus/exporters: fix regression in DynamicUser behavior 
Instead of setting User/Group only when DynamicUser is disabled, the
previous version of the code set it only when it was enabled. This
caused services with DynamicUser enabled to actually run as nobody, and
services without DynamicUser enabled to run as root.

Regression from fbb7e0c82f297815950e9153c21e561a704bfcd5.

51c3082119 nixos/prometheus: require one alertmanager configuration parameter 
This commit adds an assertion that checks that either `configFile` or
`configuration` is configured for alertmanager. The alertmanager config
can not be an empty attributeset. The check executed with `amtool` fails
before the service even has the chance to start. We should probably not
allow a broken alertmanager configuration anyway.

This also introduces a test for alertmanager configuration that piggy
backs on the existing prometheus tests.

6795bdd58c nixos/prometheus: check configuration before starting service 
With `promtool` we can check the validity of a configuration before
deploying it. This avoids situations where you would end up with a
broken monitoring system without noticing it - since the monitoring
broke down. :-)
