CLI: Update documentation for `deploy-service` native option

Currently, we can set build as native for S2I but it not precised into the help.
So, for a binary build, we could do:

$ kogito deploy-service test --native
$ mvn clean package
$ oc start-build test-binary --from-dir=target

then the runtime build is still done as a non-native build.

We should update the documentation on CLI to let the user know that `native` option is only for S2I
and also, we should add a WARN in logs if found native but not native (or the opposite)
