error: The option `services.prometheus.scrapeConfigs.[definition 1-entry 1].static_configs.[definition 1-entry 1].labels' is used but not defined.
which is unneeded, because labels _are_ optional.
The structured options are incomplete compared to upstream and I think
it will be a maintenance burden to try to keep up. Instead, provide an
option for the raw config file contents (prometheus.yml).
The collectd service runs as an unprivileged user by default, so it does
not leak more information to its data directory than any user can obtain
elsewhere by other means.
If people are running it as root and are worried about information leak,
we can add collectd group and set perms to 750.

Fixes#21198.
* influxdb module: add postStart
* cadvisor module: increase TimeoutStartSec
Under high load, the cadvisor module can take longer than the default 90
seconds to start. This change should hopefully fix the test on Hydra.
Systemd upstream provides targets for networking. This also includes a target network-online.target.
In this PR I remove / replace most occurrences since some of them were even wrong and could delay startup.
Every period, sa1 collects and stores data.
Every 24 hours, sa2 aggregates the previous day's data in to a
report.
Timers and unit configurations were lifted from Fedora's default
units.
This commit implements the changes necessary to start up a graphite carbon Cache
with twisted and start the corresponding graphiteWeb service.
Dependencies need to be included via python buildEnv to include all recursive
implicit dependencies.
Additionally cairo is a requirement of graphiteWeb and pycairo is not a standard
python package (buildPythonPackage) and therefore cannot be included via
buildEnv. It also needs cairo in the Library PATH.

Fixes#10039, at least most of it.
The `sane` case wasn't fixed, as it calls a *function* in pkgs to get
the default value.
