Merge branch 'bugfix/ejabberd_restart_config_vhost_change' of kosmos/chef into master

I have ran into an issue, changes to the LDAP config for a host are
currently only loaded on startup, not on reload

https://github.com/processone/ejabberd/issues/3181

This should be fixed once
b39a1e2d74
is part of the next release
