Dependency Management

Describe the bug

Action functions do not get called on cli.UintSliceFlag flags when set. This is because it does not have a RunAction(*Context) error function as required by the ActionableFlag interface

To reproduce

Write a simple program that uses the flag as shown below:

&cli.UintSliceFlag{
    Action: func(ctx *cli.Context, nodeNumbers []uint) error {
        fmt.Println("I am not called")
        return nil
    }
}
