Do not wait for app compute to start on bundle deploy (#2144)

## 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
