Configuring PolicyServers with proxies

PolicyServers respect the standard environment variables for dealing with proxy setups. The policy-server uses the configured proxy when downloading policies. This includes Sigstore operations when verifying policies and images.

These variables are:

• HTTP_PROXY or http_proxy: proxy server for HTTP requests
• HTTPS_PROXY or https_proxy: proxy server for HTTPS requests
• NO_PROXY or no_proxy: comma-separated list of hosts to exclude from proxying

Please refer to the PolicyServer.spec.env field of the CRD to set these environment variables.
