Describe this feature

At present, kk can't install the Linux packages in RHEL and Debian. Need repository module support for RHEL, Debian.

Describe the solution you'd like

I think the following code can solve this problem:

func New(os string) (Interface, error) {
	switch os {
	case "ubuntu", "debian":
		return NewDeb(), nil
	case "centos", "rhel":
		return NewRPM(), nil
	default:
		return nil, fmt.Errorf("unsupported operation system %s", os)
	}
}
