Adding instrumentation to debug GH actions test failures

[diverdane]

Desired Outcome

When failures during a helm install... or helm test... operation that is done as part of GitHub actions test, there should be a dump of Kubernetes resources in the conjur-oss Namespace so that we have an idea of what the system state is when the failure occurs. This will help with debugging of failed GitHub actions tests.

Implemented Changes

When a failure occurs in the GitHub actions test, the following information will be collected:

• Summary of K8s objects in the Conjur OSS Namespace
• Conjur server logs
• Conjur NGINX logs
• Postgres logs
• Node status
• Details of K8s objects in the Conjur OSS Namespace
