Setup Prelude and Kubernetes binding

Browse Source 
This change setups external dhall packages needed by the operator.
The packages are also cached in the operator image to speed up runtime.

{- This file provides a central `Prelude` import for the rest of the library to
use so that the integrity check only needs to be updated in one place
whenever upgrading the interpreter.
This allows the user to provide their own Prelude import using the
`DHALL_PRELUDE` environment variable, like this:
```
$ export DHALL_PRELUDE='https://prelude.dhall-lang.org/package.dhall sha256:...'
```
Note that overriding the Prelude in this way only works if this repository
is imported locally. Remote imports do not have access to environment
variables and any attempt to import one will fall back to the next available
import. To learn more, read:
* https://docs.dhall-lang.org/discussions/Safety-guarantees.html#cross-site-scripting-xss
This file also provides an import without the integrity check as a slower
fallback if the user is using a different version of the Dhall interpreter.
This pattern is documented in the dhall-nethack repo:
* https://github.com/dhall-lang/dhall-nethack/blob/master/Prelude.dhall
