Add support to .sequelizerc.js

[andredesousa]

Feature Description

Other tools like ESLint and Prettier have support to JavaScript, JSON, or YAML. This can be in the form of an .sequelizerc.* file. I'm just proposing .sequelizerc.js because the content is JavaScript. We will win highlighting and autocomplete.

I can open a PR if you want.

I support this idea

Hi! Thanks for the suggestion. Looks like a good idea, if you are still willing to open a PR for this @andredesousa that would be great. Maybe also incorporate a JSON file, YAML/YML file (as requested in https://github.com/sequelize/cli/issues/957) and possibly also incorporating it in package.json (as requested in https://github.com/sequelize/cli/issues/673) or in the command line in there as well? Basically just what Mocha does as well

@WikiRik I think that implementing *js is straightforward. Other formats, I need to investigate.

Not sure how much it will help you, but this is how Mocha does it; https://github.com/mochajs/mocha/blob/master/lib/cli/config.js
