support TLS config: insecure_skip_verify for PodMonitoring config

[hixichen]

with promethus config:

    - job_name: 'vault-pods'
      metrics_path: "/v1/sys/metrics"
      params:
        format: ['prometheus']
      scheme: https
      tls_config:
        insecure_skip_verify: true

Did not find any way to set the insecure_skip_verify: true from the scrapeendpoint doc

Error message:

Bumping as we are facing similar issues with our GMP instance and pulling metrics from the Kube RBAC policy. 2022/09/14 16:22:12 http: TLS handshake error from 10.30.18.133:44728: remote error: tls: bad certificate

Hi,

We are currently working on adding scrape authentication. See similar issue https://github.com/GoogleCloudPlatform/prometheus-engine/issues/241.
