Verifies that a configured resolver drives the proxy's outbound DNS
resolution. A gost HTTP proxy uses a resolver whose only nameserver is a
test responder answering echo.test with the real echo server IP and
NXDOMAIN for everything else. A request to echo.test is resolved by the
custom resolver and reaches the echo server; an unmapped host fails to
resolve. Adds a parametrized DNS responder script and container helper.
Adds 22 DNS e2e subtests across 8 test methods covering: upstream
resolution (A, AAAA, multi-A), TCP mode, bypass rules, host mapper,
exchange failure (graceful error recovery), rate limiter wiring,
invalid query handling, and DNS over TLS (mode: tls).
Includes two authoritative DNS responders (UDP/TCP), a standalone
DNS query client, and a TLS DNS query script.
Adds 12 new HTTP handler test scenarios: HTTP connector (no-auth, auth, TLS
upstream), CONNECT tunnel (no-sniffing, bypass-403), probeResist (host, web,
file, knock), idleTimeout, and UDP relay over HTTP. Introduces
RunGostContainerWithFiles helper for mounting extra files into test containers.
Docker-in-Docker containers cannot reach the internet via the default
bridge network, causing 'apk add' in the Dockerfile to hang indefinitely
and e2e tests to timeout after 10 minutes.
Add BuildOptionsModifier with NetworkMode=host to all FromDockerfile
definitions so the build step uses the host's network stack. This has
no negative impact on non-DinD environments where bridge networking
already works.
Also move GostBinPath flag and init() from main_test.go to utils.go
(non-test file) so the symbol is accessible across the package.
