Load Config From Env

[nawaitesidah]

Hello,
Is it possible to load config (host, token, email) from env var?
This is useful when using lab in a CI environment.
Or is there a way to give these values without reading from stdin?

@hadigoh I thought we had support for this, but never tried it out myself, it looks like I need add a couple more lines in main.go to make it function. I'm hoping to do a release soon and get a bunch of these relatively easy feature requests in, will include this.

  viper.SetEnvPrefix("LAB")
  viper.SetEnvKeyReplacer(strings.NewReplacer(".", "_"))

@hadigoh As a work around you can always write the lab config file and load config for that. Lab will use the config file in the current directory if present or ~/.config/lab.hcl

This is now supported in 0.12.0 with LAB_ prefix and underscores in place of . for nested keys. e.g. LAB_CORE_HOST
