Allow tcpmux (httpconnect) clients to set local_port

[green-codes]

Describe the feature request

Is it possible to allow httpconnect clients to set different local_port than tcpmux_httpconnect_port? This will open up frp to a lot more use cases, e.g. proxying port 22 to multiple SSH servers on the client side (each with different subdomains).

Describe alternatives you've considered

using static tcp port forwarding for each client-side tcp service, which is cumbersome

We plan to support this options but it has low priority.

Thanks for replying! Really hope to see this feature at some point. I manage a number of servers (some at different locations so I can’t just cluster them) behind a single frps proxy, and the port configuration is a mess. Allowing TCP mux with subdomains will be a godsend.
