[zhongnansu]

Issue #, if available:

Description of changes:

• Instead of only forwarding the security_authentication, this change will forward all cookies to handle different security setup
• rewrite the logic of https://github.com/opendistro-for-elasticsearch/kibana-reports/commit/0160a02e3a5d26b9ff279deb5831ceb71b5f8893 to pick up proxy-auth headers
• add extra required headers to handle different security setting.
