ensure that the rabbitmq-server role is assigned in rabbitmq proposals

In the future we will hopefully support HA rabbitmq, where there could
be multiple servers.

Currently there's only one possible validation error, but we follow
the pattern used by other barclamps for building an errors array and
joining it, to allow easy addition of other errors in the future.
Fix CHEF-3694 caused by bad resource naming

Two resources have the same name, which leads to:

WARN: Cloning resource attributes for rabbitmq_user[nova] from prior resource (CHEF-3694)
WARN: Previous rabbitmq_user[nova]: /var/chef/cache/cookbooks/rabbitmq/recipes/rabbit.rb:31:in `from_file'
WARN: Current  rabbitmq_user[nova]: /var/chef/cache/cookbooks/rabbitmq/recipes/rabbit.rb:38:in `from_file'
Use correct path for rabbitmq-plugins by using Config::CONFIG["libdir"]

This will make it work on more distributions (since the path might be a
bit different, depending on the distribution: /usr/lib vs /usr/lib64,
for instance).
