Some TLS servers require SNI, but the Golang HTTP client doesn't
include it in the ClientHello when connecting to an IP address. This
change adds a new TLSServerName field to health check definitions to
optionally set it. This fixes#9473.
* Add docs for MIME sniffing on metrics endpoint.
This was added in 1.7.2 last year but I realised we don't document it so it's kinda surprising Prometheus "just works" now.
* Update website/content/api-docs/agent/index.mdx
