arcgis-insights: The recipe attempts to stop portal on non-portal machines

[ptierno]

When running the cookbook on non-portal machine's I noticed that the recipe attempts to stop the portal service regardless if it is a portal machine resulting in a failed chef client run.

arcgis-cookbook/cookbooks/arcgis-insights/providers/insights.rb

Lines 65 to 74 in 6b80724

	# Stop Portal to start it later using SystemD service
	cmd = node['arcgis']['portal']['stop_tool']
	if node['arcgis']['run_as_superuser']
	cmd = Mixlib::ShellOut.new("su #{node['arcgis']['run_as_user']} -c \"#{cmd}\"", {:timeout => 30})
	else
	cmd = Mixlib::ShellOut.new(cmd, {:timeout => 30})
	end
	cmd.run_command
	cmd.error!
