Sometimes it needed, but it is better to decorate adapter.

@sampart see #261

Example of lazy adapter for Sphinxsearch engine https://github.com/Koc/Sphinxy/blob/master/Pagerfanta/Adapter/SphinxyQbAdapter.php

@mablae `LazyAdapterInterface` is present, but it is empty. It is just mark adapter as lazy.

Tests have been added

oh, no. I am talking about app cache (config, block cache, etc). Not about FPC

@phoenix128 no plans for introducing this kind of functionality?

Maybe using Symfony's approach: write serialized data + csv index with possibility show info about last N requests. Plus overwrite xmlhttprequest http://symfony.com/blog/new-in-symfony-2-6-ajax-requests-in-the-web-debug-toolbar

see https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/Profiler/FileProfilerStorage.php for more info

Please do not make response headers too big, it may cause hard to debug errors on webserver/browser side. See https://github.com/Seldaek/monolog/issues/172
