Add a separate HTTP listener for observability, configured through
metricsServer in both frps and frpc. It serves /healthz and, when
pprofEnable is set, the pprof handlers except /debug/pprof/cmdline. It
never serves the dashboard, static assets or the admin API, and it does
not touch the global assets filesystem.
frps also serves /metrics on this listener with both runtime and business
metrics, enabled by metricsServer.port alone. The in-memory collector
still starts only with the dashboard, and the Prometheus collector starts
either with metricsServer or with enablePrometheus plus webServer, so a
configuration that collected nothing before still collects nothing.
The /healthz, /metrics and pprof endpoints on webServer, and
enablePrometheus, keep working but are deprecated and log a hint at
startup. frpc does not serve /metrics yet.
Move the frpc-only TLS option into the shared TLSConfig as
transport.tls.useSystemCa, replacing the unpublished useSystemRoots.
When set, frpc verifies the server with the system CAs; when
trustedCaFile is also set, its CAs are appended to the system pool so
both are trusted. Failures to load either source abort the connection
instead of falling back. Enabling the option without effective TLS is a
configuration error, and the field is rejected in frps transport.tls
and in both webServer.tls sections.
Fixes#5545
transport.tls.trustedCaFile is installed as RootCAs, and omitting it sets
InsecureSkipVerify, so system-root verification cannot be selected directly.
Add an opt-in transport.tls.useSystemRoots that enables certificate
verification with RootCAs nil when no trusted CA file is set, allowing Go to
use system roots and native verification on macOS and Windows. Defaults are
unchanged.
