Add support for cowboy_opts config in rabbitmq.config

[SpinEternel]

Adds the possibility to use cowboy_opts configuration in the rabbitmq.config.

Unfortunately, i can't test the ssl/cowboy_opts part on my side.

Hi @SpinEternel
Thanks for the contribution!

A few minor comments, also, this should add unit tests for the change you're adding (this will also at least somewhat help with the issue you mentioned around testing the SSL variant).

I believe the tests should be something along the lines of the ones for, e.g., config_kernel_variables.

puppet-rabbitmq/spec/classes/rabbitmq_spec.rb

Lines 1587 to 1600 in 4eed5e4

	describe 'config_kernel_variables options' do
	let(:params) do
	{ config_kernel_variables: {
	'inet_dist_listen_min' => 9100,
	'inet_dist_listen_max' => 9105
	} }
	end
	it 'sets config variables' do
	is_expected.to contain_file('rabbitmq.config'). \
	with_content(%r{\{inet_dist_listen_min, 9100\}}). \
	with_content(%r{\{inet_dist_listen_max, 9105\}})
	end
	end

here is a rough example of how you can set other parameters to test different cases.

The regexes or string tests in the tests can be somewhat loose, but should be restrictive enough that they are useful.

Also, you'll need the CI checks to pass. For the case of the outdated reference file, you'll need to run the rake task to update the strings. I'd also make sure the other checks (unit tests etc.) pass locally.

Thx a lot for the help ! I didn't have a lot of time to check all the tests. All have passed, sounds good ?

Ack, sorry, meant to squish merge this one.
