Load Balancer instances get stuck if deleted and operator is not running

[carlosedp]

Describe the bug

If you try do delete the Load Balancer instances applied to your cluster and the operator pod or application is not running, the CRs get stuck because of finalizers and are not deleted until the operator runs.

To override this, patch the CRs removing the finalizer with the command kubectl patch externalloadbalancers externalloadbalancer-infra-sample -n lbconfig-operator-system -p '{"metadata":{"finalizers":[]}}' --type=merge using your CR name.

To Reproduce
Steps to reproduce the behavior:

1. Deploy the operator
2. Create CRDs for a LB instance and a backend (with secret)
3. Stop/remove the operator PODs
4. Delete the LB CRs

Expected behavior
The CRs should be deleted.
