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
