No, there is no such configuration option. You'd have to extend the
sources of load tester.

Load tester does not use OpenSSL to generate the certificate, but our
own routines from libstrongswan. To add additional attributes to client
certificates, pass BUILD_* arguments to [1]. See [2] and [3] to read
more about how the credential building facility works.
