## Current Behavior
<!-- This is the behavior we have today -->
The `@nx/webpack/plugin` will resolve and read webpack options from user
defined config files.
However, it does not set the env vars indicating that a task is being
run, because tasks are not being run at this stage.
This means that certain config properties are not being set by
`applyBaseConfig`.
Users' webpack configs may rely on these properties being set so they
can modify them.
When not set, this throws, meaning the graph cannot be constructed.
## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
Initialize the properties that we usually set when `applyBaseConfig` is
used.
