ws port config for custom bundles

[nphias]

so after adding our bundle to holoscape throught the UI wizard
realized the links were hardcoded to a WS port.
in the docs
HOLOSCAPE_ADMIN_PORT 4436

changed the static files ws port to 4436 and it worked.
in the bundle config file it would be nice if you could choose the websocket port for your happ
later I realized that one can change the port in the condutor_config.toml in the relevant OS install directory. Its a post install task... which could be documented better

so i keep this issue open for a potential pre-install feature or for clearer documentation post install

This can be fixed by removing the websocket url argument from hc-web-client. When you remove that argument, hc-web-client looks for the port specified in conductor-config.toml instead.

I also find this is an under-documented thing.

Our acorn-ui project uses this configuration, where our webpack config adds a NODE_ENV distinction between 'development' and 'production' so that we can pass the right thing to our connect call, from hc-web-client.
