From: Numan Siddique <nusid...@redhat.com>

Centos provides pyOpenSSL version pyOpenSSL-0.13.1-3.el7.x86_64.
There are 2 issues using this version, which this patch fixes

 - The test case "simple idl verify notify - SSL" is skipped.
   This is because "python -m OpenSSL.SSL" is used to detect the
   presence of pyOpenSSL package. pyOpenSSL v0.13 has C python
   modules because of which the above command returns 1.
   So this patch fixes this by using 'python -c "import OpenSSL.SSL"'.

 - The SSL.Context class do not have the function "set_session_cache_mode"
   defined. Setting the session cache mode has an effect for server-side
   sessions and doesn't make much sense for client-side sessions.
   Since python ovs doesn't support "pssl" connection mode, this patch
   deletes the reference to this function.

I have not tested with older versions (< 0.13) of pyOpenSSL.
