make some setting configurable

[n-able-consulting]

🚀 Feature

Running Hocus on my machine returns:
Error response from daemon: driver failed programming external connectivity on endpoint hocus-local-temporal-ui-1 (cbc62ebf21e7d4809eeae9d689060319db484d77827cc32bbb1f2383370580b2): Error starting userland proxy: listen tcp4 0.0.0.0:8080: bind: address already in use

Because I already use a lot of software & reverse-proxies.... So 8080 is already bound.
Would be nice if I could simply change this setting (a.k.a. make it dynamic from a central place)?
Without figuring out what you have build and how you have set it up yourselves.
