k8s 1.18 fix

[ukclivecox]

What this PR does / why we need it:
Allows Seldon Core to be deployed on k8s >=1.18

• Adds a v1 CRD to kustomize.
• Updates helm to choose between v1beta1 and v1 CRDs based on k8s version.
• Adds a script to generate graph childen to a greater depth. Unfortunately references are still not allowed in OpenAPISchema and anyway this structure is recursive.

Notes:

• v1 CRD is structural.
• v1 CRD does not need volumes hack due to k8s fixes in k8s 1.18

Which issue(s) this PR fixes:

Fixes #1675
Fixes #926
Fixes #1864
Fixes #641

Nice one! I've tested in kubernetes 1.18 and Kubernetes 1.12 and can confirms it works as expected.

Two things that would be good to add issues for to follow up:

• Pinning the version of the integration tests to k8s 1.18 (or a specific version
• Updating the operator and executor golang dependencies to 1.18 (from 1.17)
