Use kube-bench to audit kubernetes configuration

[v1r7u]

The initial solution should consist of two parts:

• scheduled job, which can run kube-bench and store raw result in configured blob-storage
• GET /api/kube/{kube-cluster-id}/bench HTTP endpoint to get latest results from blob for particular cluster, normalize and return a summary object with array of check-results

The job should run in k8s cluster. Required scripts, code, and configuration to execute it should be located at this repo in /scanners/kube-bench folder.

Blob Storage files structure should follow:

/
|-kube-bench_{kube-cluster-id}
.   |-metadata
.   |-results
.      |-{year}_{month}_{date}_{hours}_{minutes}_{seconds}.json
.      |-...
|-kube-bench_{kube-cluster-id}
.   |-metadata
    |-...

metadata - json file, which has technical information about the task, like last_executed_at, scheduled_periodicity, and others.

For the first iteration, credentials to get access to the blob storage are provided through env-vars
