[10.x] Add strict option to hasColumns function

[ariaieboy]

I usually test my database schema using the hasColumns method and ensure all desired columns exist on my database.

However, this method changes the column's name and does not check the order of columns.

I've added a simple strict param that will check the columns against the given columns array that is passed to the hasColumns function.
