Added support for passing params to Varnish Daemon with a Ruby array in chef, usage example:

In attributes:

	default['varnish']['daemon_parameters'] = [
		'pipe_timeout=600',
		'listen_depth=4096'
	]

In recipes:

	node['varnish']['daemon_parameters'] = [
		'pipe_timeout=600',
		'listen_depth=4096'
	]
