Client: handle pagination, default to 500 items per page, automatically paginate additional pages

[glaubinix]

Pagination isn't part yet of the public API of the client, so wouldn't document this here just yet

Testing Instructions

• Might be easiest to set the LIMIT to 1
• Fetch all items of a resource where you have more than one
• Assert that multiple requests have been made
• Assert that the return value is still the same

Changing this after our discussion regarding the max_restarts option in PluginChain: without changing that configuration, this plugin will cause an exception to be thrown after the 10th page. Probably better to just handle this directly in our own code.

this is now so much more readable! Thanks :)
