added: configuration for Pleroma

This merge request adds the template file and default variables for
configuring Pleroma.
Also included in this merge request are:

- added: Makefile to produce the secret key base, signing salt and the
public and private keys for web encryption.
- fixed: Pleroma OTP builds are now downloaded from the stable branch.
- changed: removed data from the pleroma task and added them in the
variable directory.
