Issue 164: Pre_Install_Report : Update deprecated Kubernetes APIs in tool to be compatible with Viya supported range 1.20.x-1.22.x

[lasiva]

Updates:

• viya4-ark/pre_install_report/library/utils/crdviya.yaml - uses apiextensions.k8s.io/v1viya
• viya4-ark/pre_install_report/library/utils/crviya.yaml
• viya4-ark/pre_install_report/library/utils/hello-ingress.yaml
• Added k8s version at the top/global section of the Report (Currently user would have to drill down to find it). Moved Version check code earlier so that it is detected earlier. Should help with future maintenance.
• Added k8s version to logs.
• Updated README to reference to latest SAS Doc for Kubernetes Cluster requirements. (Will require frequent updates with the link to SAS Doc.)
• Fixed Minor Type in logging message, https://github.com/sassoftware/viya4-ark/issues/162

Deleted support for <1.19.

• Deleted hello-ingress-k8s-v118.yaml - no longer supported.
• Removed related pytests.
• Refactored old code related to k8s version checking.

Questions: There are no checks for upper limit of k8s supported range. Do we need one ???
