Description of the change
These changes add support for usage of environment variables in Yaml config files(currently only enabled in the Config module).
PyYaml supports node tagging, so this uses a custom constructor that replaces nodes tagged with
!ENVwith an environment variable with the same name.This step will explicitly error if a variable is not set.
Example:
The value for
foowould be set to the value of the MY_VAR variable.Type of change
