all: refactoring the hosts blocks format and location
This changes add new directory called "block.d" under rescached. This directory contains hosts file fetched from URL defined in hosts block configuration. In this way, we did not mixed between user created hosts file and external hosts file. In the configuration file, we changes the hosts block format from single line hosts_block = <URL> into subsection with dynamic name, [block.d "<name>"] name = <name> url = <URL>
