Removed old CA cert/key pair and /certs/ directory (we're storing issued certs in redis).
Ignore test CA cert/key.

Don't want to include these in the repo as they'll write over the ones in production if pushed.
Modified config.yaml with new certificate names, included client profile for signing client certs.
Removed old test CA cert.
Updated capistrano to create symlinks to production cert/key after deployment completes.
