{# key_url fetch by curl when salt <2017.7, higher version of salt has
   fixed bug for using a proxy_host/port specified at minion.conf

   NOTE: curl/cmd.run usage to fetch gpg key has limited functionality behind proxy.
         Environments with salt >= 2017.7 should use key_url specified at
         pkgrepo.manage state (which uses properly configured http_host at
         minion.conf). Older versions of salt require to have proxy set at
         ENV and curl way to fetch gpg key here can have a sense for backward
         compatibility. Be aware that as of salt 2018.3 no_proxy option is
         not implemented at all.
