KT_DEFAULT isn't appropriate for this test - we need to test each permutation of
{RSA, ECDSA} -> {RSA, ECDSA} for client and server.

[torbjorng (webrtc), 2015/07/02 12:35:08]

Makes sense. I enable testing using TEST_P for all most tests in this file.

GetDefaultSslCipher needs to take KeyType as a parameter.

[joachim, 2015/06/30 20:15:24]

Yes, please don't hardcode cipher names in the tests but let the
SSLStreamAdapter decice which cipher to use for the protocol-version/key-type
combination.
