Layerform should just create the local context directory instead of erroring out

[vieiralucas]

When the user configures a context of type local it also has to provide the dir for the state and definitions to be saved to. Currently, if that directory is non existing, layerform just errors out, see video.

configure-invalid-context-dir.mov

To fix this, we should just add code before this os.WriteFile below to ensure the directory exists. Just use os.MkdirAll
