Kostiantyn Kalynovskyi a6987107bd Allow to perform phase render using document entrypoint
In current setup, we rely on executor to perform render operation,
however there are many usecases, when we want to have a simple
`kustomize build` performed against document entrypoint in phase.
Now this will be a default behaviour and if a user would like
executor to perform rendering to actually understand what it's
doing, he will be able to specify --executor boolean flag.

Relates-To: #403
