The insights-client connects with cert-api.access.redhat.com and fails with an SSL error since updating the insights core version to 3.6.7

Issue

• Since the release of insights core 3.6.7, every execution of the insights-client command shows the following behavior:

  # insights-client 
  Starting to collect Insights data for rhel.example.com
  HTTPSConnectionPool(host='cert-api.access.redhat.com', port=443): Max retries exceeded with url: /r/insights/platform/inventory/v1/host_exists?insights_id=xxxxxxx-a643-48d0-8f4f-xxxxxxx (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1147)')))
  The Insights API could not be reached.
  Writing RHSM facts to /etc/rhsm/facts/insights-client.facts ...
  Uploading Insights data.
  Successfully uploaded report from rhel.example.com to account xxxxxx.
  

• The problem is visible only for the RHEL systems that have the insights core version updated to 3.6.7 and are being managed by a Red Hat Satellite/Capsule server.
