Matthew HoltandCopilot fe69f5da2d caddyhttp: enforce bounded host metric labels on HTTPS ...

With per_host metrics, HTTPS servers automatically observed catch-all
hosts, and port/case variants of configured hosts produced distinct
labels. Require explicit observe_catchall_hosts for unconfigured hosts,
normalize the host label, and also collect hosts from subroutes, error
routes and named routes (scanned after handlers are provisioned).

Behavior change: unconfigured hosts on HTTPS servers are now labeled
"_other" unless observe_catchall_hosts is enabled.

Addresses scan report 457dcf090b421495.
