Utilize the k8s-reporter in the e2e tests

[liornoy]

Modify the k8sreporter/reporter.go to utilize
the latest external k8s-reporter package.

The new reporter still outputs the same output as before plus the CRDs: SriovOperatorConfig and SriovNetwork.

It is used by the conformance and validation suites, consumes the flag "-report" as the path to where the dir "sriov_failure_report.log" will be created and hold all of the failed tests logs.

Here is an example of the k8s reporter tree output when all the tests of the validation suite failed:

.
└── sriov_failure_report.log
    ├── validation_sriov_should_deploy_the_injector_pod_if_requested
    │   ├── crs.log
    │   └── nodes.log
    ├── validation_sriov_should_deploy_the_operator_webhook_if_requested
    │   ├── crs.log
    │   └── nodes.log
    ├── validation_sriov_should_have_SR-IOV_node_statuses_not_in_progress
    │   ├── crs.log
    │   └── nodes.log
    ├── validation_sriov_Should_have_the_sriov_CRDs_available_in_the_cluster
    │   ├── crs.log
    │   └── nodes.log
    ├── validation_sriov_should_have_the_sriov_namespace
    │   ├── crs.log
    │   └── nodes.log
    └── validation_sriov_should_have_the_sriov_operator_deployment_in_running_state
        ├── crs.log
        └── nodes.log

Where the crs.log will dump all of the CRDs,
nodes.log is the list of nodes objects in json format,
and in case pods exist in the sriov namespace, it will dump
for each test: pods_logs.log and pods_specs.log
