Documentation fix - TOML usage

[bscott]

Documentation only shows how to use default.toml, not including user.toml

habitat/components/sup/src/service_config.rs

Lines 337 to 340 in 7a95707

	try!(cfg.load_default(pkg));
	try!(cfg.load_user(pkg));
	try!(cfg.load_gossip(pkg));
	try!(cfg.load_environment(pkg));

environment.toml isn't a thing, this code loads environment variables. We're definitely missing docs on user.toml though.

Thanks!

[bscott]

@metadave thx I'll update issue, meant to just keep user in the desc.

[bscott]

@metadave Any preference where I can put the user.toml documentation in the docs?

[bookshelfdave]

@bscott lets get @davidwrede's input on that

[bookshelfdave]

what are your thoughts on putting them somewhere under https://www.habitat.sh/docs/run-packages-overview/ ?

[davidwrede]

@bscott, as @metadave suggested, under run-package-overview probably makes the most sense. We can always tweak and move it around later if needed.

[bscott]

@davidwrede Ok thanks

To clarify, user.toml is for user defined overrides of config settings.

@bscott any progress on your work documenting user.toml? :)

[rsertelon]

Shouldn't it be in https://www.habitat.sh/docs/using-habitat/#config-updates now?

[tashimi]

Yes, this looks good now. Thanks @rsertelon!

[asymmetric]

@tashimi AFAICT there's still no mention of the user.toml on this page, isn't that what this issue was about?

[rsertelon]

@asymmetric issue #3977 opened by @christophermaier is in the direction you suggest here IMHO.
