RabbitMQ should get pinned on Debian based systems

[tas50]

A version pin for apt should be created on Debian based systems. This prevents the user from upgrading the package and then Chef downgrading the package on the next chef run. A lot of cookbooks use this pattern and it provides a nice gate to version upgrades / prevents downgrade problems.

Are you suggesting adding it as another attribute? Seems like a straight forward PR/spec to add.

I'm assuming something like:
https://github.com/jjasghar/rabbitmq/blob/master/recipes/default.rb#L36

Granted @wenchma Just put in: #177 which i think fulfils your requirement.

@tas50 I created I created: #180 to attempt to resolve this issue.

[jjasghar]

@tas50 any chance to look at #180?
