Niklas Ye bde5611b16 Let a TerdutServer turn on metrics from the alerts' Prometheus
terdut-server v0.49.0 graphs the metric behind each alert on the incident
page, but only queries hosts listed in TERDUT_PROMETHEUS_ALLOWED_HOSTS,
because the URL comes out of a webhook payload. An install this operator
creates had no way to set it short of spec.pod.extraEnv.

spec.prometheus takes allowedHosts, preroll and timeout and maps them to
TERDUT_PROMETHEUS_ALLOWED_HOSTS, _PREROLL and _TIMEOUT. Nothing is emitted
unless allowedHosts is non-empty, so existing TerdutServers get the same
Deployment as before, and unset durations are left to the server's defaults.
There is no CRD default for the host: which Prometheus to trust is the
deployer's call, not something this operator should assume.

The CRD in config/ is regenerated and the chart's copy carries the same
schema; the chart's optional TerdutServer passes the block through.
