Feature: Make timestamp optional

[adeelhussain]

What you are doing?

sequelize model:generate --attributes as --name modelName --attributes firstName:string

What do you expect to happen?

I would like to make the timestamp optional because for some tables, there is no need of that.

What is actually happening?

Right now its adding createdAt and updatedAt in every migration file of creating table

There should be a flag something like this

sequelize model:generate --name modelName --attributes firstName:string --timestamp false

which will skip the timestamp
