Push APIs to HTTPS registry without ignore TLS - x509: certificate signed by unknown authority

[renuka-fernando]

Description:

1. Deploy APIs to HTTPS registry

Without applying the following kaniko args, should be able to deploy the API.

kanikoArguments: |
--skip-tls-verify
--skip-tls-verify-registry
--skip-tls-verify-pull

SOLUTION Kaniko pod should be included with the crt of HTTPS registry.

2. Update Docs

Update docs for including certs when deploying APIs to HTTPS (this is need when the operator is trying to check if the API already exists in the repository).

1. Include the cert of the docker registry to the ca-bundle with existing certs.
2. Add a volume as below to the operator.yaml

   spec:
     serviceAccountName: api-operator
     containers:
       - name: api-operator
         # Replace this with the built image name
         image: testRepo/k8s-api-operator:1.2.2
         command:
         - api-operator
         imagePullPolicy: Always
         env:
           - name: WATCH_NAMESPACE
             value: ""
           - name: POD_NAME
             valueFrom:
               fieldRef:
                 fieldPath: metadata.name
           - name: OPERATOR_NAME
             value: "api-operator"
         volumeMounts:
           - name: certs
             mountPath: /etc/ssl/certs/ca-bundle.crt
             subPath: ca-bundle.crt
     volumes:
       - name: certs
         configMap:
           name: certs
