Adjusting grafana interface as multiple fault injections were removed from documentation.

Reorganizing the repo structure to match the plan. Apparently, git filter-branch was not necessary to remove certificate's private key because someone had already run it. At least, git log --diff-filter=D --summary | grep delete does not show any private key.

Most of the differences were related to the fact that aggregators are not already available on sv3.
The Backend differences were innocuous (spaces, indentation, and blank lines).
Config changes consists on email and log address.

Updating bin/smartdata/Aggregators.php to add Aggregators to developed on 2019-2.
Updating lib files to include those aggregators.
Uploading the smartdata_grafana_plugin, with the code that when compiled generates the lib folder.
Lib folder's content is the one we put on the server. This content is generated using the plugin code, that was originally placed at https://epos.lisha.ufsc.br/svn/makers/smartdata_grafana_plugin/.
A tutorial of how to do this process is available at https://epos.lisha.ufsc.br/IoT+Internals#Grafana_Integration. However, it is a bit outdated. Should I update the page at epos site or create a README inside the plugin folder on gitlab?
