Ability to configure a redirect to an arbitrary URL

[vonZeppelin]

Describe the Feature

Support configuring a redirection to an arbitrary URL as the default action of an ALB.

Expected Behavior

ALB supports configuring a redirection to an arbitrary URL and to a modified URL, but only HTTP -> HTTPS redirection can be set with this module currently.

Use Case

For example, SaaS app's ALB default action can be a redirection to a company's website.

Describe Ideal Solution

The module has an input variable(s) to configure URL redirection.

Alternatives Considered

A fixed HTML response with <meta http-equiv="refresh" content="0;URL='https://acme.com'" tag can be used to redirect to an arbitrary URL for cases when ALB's main client is a web browser.
