removal of spring-cloud-kubernetes-fabric8-istio

[wind57]

We have this dependency spring-cloud-kubernetes-fabric8-istio.

To be honest, I don't understand its usefulness and I think we should sunset it in the next major.

I have a few arguments for this decision:

• we have not received any requests for istio functionality in the last few years
• we do not have a k8s-client equivalent
• the only useful thing it does is setting a profile called istio that potentially users can use, but again, we have not received any requests or issues or bugs in this regard.

If someone really needs this, I would gather the specific requirements from them and start clean.

wdyt?
