Add current path in ESI requests

Problem/Motivation

When ESI blocks are called, we cannot know which page call the block.
In case a block needs a context, like the current node displayed, we cannot get it from ESI block.

Steps to reproduce

Add a block which load a node from current route and display node title. Configure block to be loaded with ESI.
We cannot get current node from ESI block.

Proposed resolution

Give current path or route when ESI url is called
