Errant warning provided when specifying alternative bosh env on genesis new

[dennisjbell]

When explicitly stating the bosh env (--bosh-env X), genesis new should not warn that it is defaulting to using bosh deployment method.

/ops/bosh ∴ genesis new rsat-bc-genesis-ci --bosh-env rsat-bc-ops
Verifying availability of vault 'rsat-bc-ops' (https://172.20.0.16)...ok

Setting up new environment rsat-bc-genesis-ci based on kit bosh/3.0.0 ...

[WARNING] Kit bosh/3.0.0 supports both bosh and create-env deployment.
          No --create-env option specified, so using bosh deployment method.

Is this a proto-BOSH director? [y|N] >

Furthermore, but this is more directed at the bosh kit's hooks/new script, it shouldn't be asking if it's a proto-bosh (outdated terminology and it already knows it isn't)...
