## Changes
Added a warning when `config` section is used in apps
## Why
To avoid the confusion between using apps in DABs and outside of DABs,
we want to provide only one way of configuring apps runtime
configuration - by using `app.yml` file in the root of the app.
## Tests
Added acceptance tests
$VARNAME is what we use for environment variables, it's good to
separate.
Some people use envsubst for homemade variable interpolation, it's also
good to have separation there.
## Changes
This allows DABs to avoid waiting for the compute to start when app is
initially created as part of "bundle deploy" which significantly
improves deploy time.
Always set no_compute to true for apps
## Tests
Covered by `TestDeployBundleWithApp`, currently fails until TF provider
is upgraded to the version supporting `no_compute` option
