Improve salt setup

This commit improves the salt setup of the Vagrant box:
- Salt output is reduced to log level warning
- Hosts entries are created for the internal IPs of all planned gva
  component VMs
- .bashrc and a .bash_functions sourced from it are now managed for the
  vagrant user
- the VM name has been changed to gva.local
- recent salt versions do not depend on m2crypto anymore, therefore it
  is now installed before x509certificate functions are called
- the rabbitmq_vhost for gva is now setup before any users are created
  because the previous implementation was broken with recent salt
  versions
- the gnuviechadmin-locale-data-compile step has been simplified because
  Django 1.9's compilemessages takes care of recursive .mo file
  compilation
- pillar data has been separated by role (especially queue permissions
  and credentials)
- salt configuration is now unified with gvaldap
