feature request: ziti-tunnel host

[qrkourier]

With ziti-tunnel proxy on Windows and MacOS it is necessary to provide at least one service name on the command line like ziti-tunnel proxy "Gettin' Ziggy Wit It":54321. If my goal is merely to host a service with tunneler then there's no motivation for me to bind a service by name to a local port. It might make more sense to add a mode like ziti-tunnel host that simply doesn't require or allow binding a service, and so will only host services.
