Class-based reconcilers can't be hosted in one binary with HA

[markusthoemmes]

/kind bug

Expected Behavior

I can host as many class-based controllers (for example: Ingress reconcilers) as I want in a binary, as long as the classes don't clash.

Actual Behavior

They try to get the same lease and thus only one really works. This is quite similar to #1979.

Steps to Reproduce the Problem

1. Create a binary that launches two Ingress reconcilers
2. Launch it and see how it competes for the lease.

Additional Info

This is quite similar to #1979.

I guess the simplest way of fixing it is adding the class filter to the lease name.
