ipatests: display SSSD kdcinfo in test_adtrust_install.py
The test test_adtrust_install.py::TestIpaAdTrustInstall::test_add_agent_not_allowed
sometimes fails at kinit in create_active_user:
```
kinit: Password has expired while getting initial credentials
```
krb5_strace shows that this happens when kinit changes servers
between password change and TGT requests.
Display SSSD's kdcinfo to see if kinit should be pinned to one
server.
