support project from js files

Resolves #383

[ianhe8x]

Code of user's project are considered high risky and untrusted, therefore we restrict their execution in sandbox only, your pr expose vulnerability in the system. So not going to be accepted sadly.

[ianhe8x]

After a second thought, since my concerns are mostly security concern for require(filePath). If you can wrap it in the sandbox, most of them will be solved.

@amphineko are you happy work on this further?

[amphineko]

@jamesbayly We have solved this problem using a different approach. project.yaml will be re-configured automatically by gulp via npm prepublish or during container startup.

on container startup:
