Hi@kinsi55 ! First of all, thanks for contributing!
I think it's a good feature!

Well, there are a few little bits to make this PR better:

• Will be great, if you extend README with an example of modelDefaults as object.
• There is no test for this new feature. I'm trying to cover all code with tests, and especially new ones. So we can be sure it will work as expected in the future.

I was just trying to get this out quickly as I've wanted to use it myself. I'll try to add a test for it / extend the readme when I get around to it. If you happen to be interested in doing it you're ofc free to do it :P Dont know when I'd get around to it.

I don't think it's gonna take long! ;)
Just a simple example with a few common options + 1 test, that checks that options are propagated to models ;)

I've a question - when using this hook / Sequelize doesnt it essentially prevent you from using the normal ORM / Waterline alongside? If so I'd just switch it to using sails.config.models instead of the custom key as that makes things more streamlined.

Well, it's possible to use both: sequelize and waterline models at the same time.
I don't think it's a good idea to store sequelize configuration in sails.config.models as it is supposed to be used in waterline. Also, keys and options may differ, so let's save it separately.

Found out that Sequelize can do this using the beforeDefine global hook (seesequelize/sequelize#4383)

Example:

   options: {      dialect: 'postgres',      host   : 'localhost',      port   : 5432,      logging: console.log, // or specify sails log level to use ('info', 'warn', 'verbose', etc)      hooks: {        beforeDefine: (attributes) => {          attributes = Object.assign(attributes, {            createdAt: { type: Sequelize.BIGINT, field: 'created_at' },            updatedAt: { type: Sequelize.BIGINT, field: 'updated_at' },          });          sails.log("beforeDefine", attributes);        }      },   }
