Please add more descriptive error message for hostWhitelist property in environment.js

I do believe we can add a link to that error message so we can point users in the correct direction, thanks!

@danmcclain Ah, thanks! I only read the README 👍

[danmcclain]

The website is the canonical place for usage information, we shifted away from the README, as it would get unwieldy

[danmcclain]

hostWhitelist is discussed in the User guide here: http://ember-fastboot.com/docs/user-guide
(no link to the proper section, sorry).

Will this message also be displayed if there is a whitelist but the host is not on it? Or will there be a different message? If the same message is used for both, providing a more specific message that identifies the host that failed the match would be helpful.

Two small changes to the manual might help with this:

It is very, very easy to put the fastboot:{} in the wrong part of the environment.js. Sounds like the OP was having some confusion about that. In the manual, putting it above the EmberENV: {} and App: {} rather than below them might make it clearer that it has to appear at the let ENV: { ... here ... } level. I had to read it a few times to be sure of that myself.

Also, while ember serve will detect environment.js changes and rebuild the project, I think fastboot may not be picking up its changes under that condition. I had better luck stopping ember serve and restarting it, but I only discovered that by accident after making repeated changes and wondering why I was still getting the error.

Any chance of actually updating this error message as @danmcclain suggested? It's 2020 and the error message is still pretty cryptic. :)
