Subject: [PATCH BlueZ v2 4/5] test/mesh: Add support for testing more OOB auth

To pass IOP testing, we need to be able to support Input OOB and Out of
band Public Key exchange,  This patch adds agent methods to support
those capabilities, but are turned off because the test code uses
insecure fixed values instead of randomized values.
