make image digest available in setters

Using the new `:digest` suffix in policy markers one can now instruct IAC to store the digest of an image instead of the tag in the given manifest. This makes use of the the `.status.imageDigest` field introduced in fluxcd/image-reflector-controller#368. closes #165 Signed-off-by: Max Jonas Werner <[email protected]>
