Bug description:
  == Begin SRU Information ==
  [Impact] 
   * a documented feature of cloud-init, for adding ca-certificates does not function as it should.  Instead, certificates added in this manner simply are ignored.  This is because apparently, a line directly following a blank line in /etc/ca-certificates.conf is ignored.

  [Test Case]
    - start a cloud instance with no user-data
    - add content below to /etc/cloud/cloud.cfg.d/99-local-certs.cfg
    - run the ca-certs code through cloud-init single
      you will see output from update-ca-certificates indicating no
      new certificates were added
      $ sudo cloud-init single --name=ca_certs --frequency=always
      Cloud-init v. 0.7 running 'single' at Sun, 02 Dec 2012 02:23:21 +0000. Up 2429.68 seconds.
      Updating certificates in /etc/ssl/certs... 0 added, 0 removed; done.
      Running hooks in /etc/ca-certificates/update.d....done.

      # this can be fixed by removing the blank line and re-running
      # update-ca-certificates
      Also, note that the following has no output:
      $ ls -l /usr/lib/ssl/certs/ | grep -i cloud
    - edit /etc/ca-certificates.conf, remove cloud-init added entry
      $ sed -i '/cloud-init-ca-certs.crt/d'
    - upgrade cloud-init, re-run the ca_certs
      $ sudo dpkg -i cloud-init_all.deb
      $ sudo cloud-init single --name=ca_certs --frequency=always

      This time, you will see output containing: "1 added, 0 removed; done."
      Also, (trimmed output), you will see:
      $ ls -l /usr/lib/ssl/certs/ | grep -i cloud
      lrwxrwxrwx b1d2b355.0 -> cloud-init-ca-certs.pem    
      lrwxrwxrwx cbbf81bb.0 -> cloud-init-ca-certs.pem    
      lrwxrwxrwx cloud-init-ca-certs.pem -> /usr/share/ca-certificates/cloud-init-ca-certs.crt

  [Regression Potential] 
   * regression potential is low.  It could break the ca_certs module further, but the module is not functional as it is. Tracebacks are caught when modules are executed, so there is really no potential for further harm.

  == End   SRU Information ==

  Using a cloud-init yaml file adding a certificate like this:

  # BEGIN /etc/cloud/cloud.cfg.d/99-local-certs.cfg
  ca-certs:
    # If present, the 'trusted' parameter should contain a certificate (or list
    # of certificates) to add to the system as trusted CA certificates.
    # Pay close attention to the YAML multiline list syntax.  The example shown
    # here is for a list of multiline certificates.
    # - Amazon RDS SSL Certificate (http://s3.amazonaws.com/rds-downloads/mysql-ssl-ca-cert.pem)
    trusted:
      - |

  # END /etc/cloud/cloud.cfg.d/99-local-certs.cfg

  The certificate is added to the /etc/ca-certificates.conf file but
  there is a blank line between the previous content and the line added
  by cloud-init.  In this situation running update-ca-certificates
  doesn't take the cloud-init certificates into account.  Removing the
  blank line and running update-ca-certificates again fixes the issue.
