Cannot set delivery-limit policy

[philomory]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 5.5.18
• Ruby: 2.4.4
• Distribution: CentOS 7
• Module version: 10.0.0

How to reproduce (e.g Puppet code you use)

rabbitmq_policy { 'example1@/':
  pattern    => "^example1$",
  priority   => 50,
  applyto    => 'queues',
  definition => {
    'delivery-limit' => 3,
  },
}

rabbitmq_policy { 'example2@/':
  pattern    => "^example2$",
  priority   => 50,
  applyto    => 'queues',
  definition => {
    'delivery-limit' => '3',
  },
}

What are you seeing

For the integer delivery-limit:

Error: Failed to apply catalog: Parameter definition failed on Rabbitmq_policy[example1]: Invalid definition, value 3 is not a string 

For the string delivery-limit:

Error:
Validation failed

<<"3">> is not a valid delivery limit

What behaviour did you expect instead

I should be able to set a delivery limit via policy with the RabbitMQ module.

Any additional information you'd like to impart

I can see in the code that the module expects all policy values to be Strings as they come in from the manifest, and the Type munges a select whitelist of values to integers; obviously delivery-limit could be added to this whitelist, but, I wonder if it wouldn't make more sense to instead stop trying to enforce stringiness in the first place - example 1 should be allowed to 'just work', without the module needing to be aware that the delivery-limit policy takes an integer.
