The two docker compose files for ARM based systems were not configured to pass the auth_proxy variables through to the gateway at deploy time.  This was causing an error in the gateway which would manifest in the CLI and UI as: `ExternalAuthHandler: Get : unsupported protocol scheme ""`.

This change adds `auth_proxy_url` & `auth_proxy_pass_body` to the two ARM compose files so as to mirror the config of the x86_64 compose file.
