Add options for SSL support either via files or FreeIPA

Updated patch to work against current master. This branch in my repo was rebased against master and force-pushed. The top SSL patch should apply cleanly against master, the rest is just noise.

Enabling SSL is slightly more difficult now in that it requires careful editing of bin/seeds.rb.

This patch is largely the same as the past submitted last year with the addition of configuring heat and cinder to use the SSL-enabled mysql server.
