snowflake-proxy doesn't write any files
=> run in read-only rootfs environment
the process needs to read SSL certs but no other files
=> only exposed path is /etc/ssl/certificates (read-only)
running as unpriviledged user with no additional capabilities
=> set no-new-privs bit
By default procd-ujail also isolates the process by executing it in
a separate new IPC and PID namespace.
