all: change the HTTP API to update hosts in block.d

We have HTTP API to enable or disable block.d by batch by passing all
block.d records.
The name of HTTP API is /v2/block.d/update and this is duplicate with
API to update the content of hosts in block.d.

This changes fix this by creating new HTTP API /v2/block.d/fetch
that fetch the latest hosts file from specific block.d by its name.

While at it,

- reformat html and JavaScript files using js-beautify
- rename constants and methods for HTTP APIs
- add and update comments for some HTTP APIs
