Add support for model:generate --name User role:enum:{Admin, Guest}

Closes #550

Hello!
Thanks for this great tool. I was curious about enum support and discovered that I was not the only one. I took a first pass at it here. I imagine there is somewhere I should also be adding docs for this, so definitely let me know and I'll add them on to this PR. Let me know what I might need to adjust. 🎃

Best,
Mike

Looks good, you can add an example here https://github.com/sequelize/cli/blob/master/docs/FAQ.md#how-can-i-generate-a-model

@sushantdhiman I updated the FAQ with the additional enum. Thanks for pointing me in the right direction.

Am I crazy or does this cli syntax NOT work at all?

This is what I type into my terminal:

sequelize model:create --name Customer --attributes id:integer,nameTitle:enum:{Mr,Mrs,Miss,Ms,Dr,Prof},nameFirst:string,nameMiddle:string,nameLast:string

Result:

ERROR: Attribute 'nameTitle:enum:Mr' cannot be parsed: Unknown type 'Mr'

Hi @achacttn
I have a hunch your shell is modifying it. Try:

sequelize model:create --name Customer --attributes 'id:integer,nameTitle:enum:{Mr,Mrs,Miss,Ms,Dr,Prof},nameFirst:string,nameMiddle:string,nameLast:string'

or...

sequelize model:create --name Customer --attributes id:integer,nameTitle:enum:\{Mr,Mrs,Miss,Ms,Dr,Prof\},nameFirst:string,nameMiddle:string,nameLast:string

Unfortunately, that's probably going to confuse a fair amount of people. I'll post an update to the documentation. Thank you for letting me know.
