allow ports to be specified in vhosts

[dovholuknf]

right now, it doesn't seem like vhosts can have ports included at the end. on top of that, if i wanted to use port :443 or :80, browsers will remove that port number. That situation should work as well

The vhost property in a target map within targetArray?

@dovholuknf I assume you're referring to the vhost property in one of the targets defined in the ZITI_BROWZER_BOOTSTRAPPER_TARGETS env var.

Are you considering a scenario where a request HOST header contains a port different from the Bootstrapper's load balancer port?
