Request: Configurable DevServerManager port

[terussell85]

I'm not sure if this is possible given the comments on #42 , but I'd bring it up, since I'm surprised no one else has run into it..

Having the dev server port hardcoded to 8080 in ports.ts (https://github.com/HubSpot/hubspot-local-dev-lib/blob/main/constants/ports.ts#L4) make configuring local dev environments difficult. Many backend frameworks default to 8080, so there are naturally conflicts.

In our case, we have a public HubSpot app that we are developing locally that needs to connect backend services (also running locally). The proxy functionality in the hs cli. Because we already have a service running at 8080, in order to run the hs project dev command, we have to reconfigure our entire port mapping for our micro-services. Not impossible, but not ideal either.

It'd be really nice if DevServerManager supported a configurable port so that it can be used in the cli when running. hs project dev.
