http: Support chunked request bodies

This is a temporary support for chunked request bodies by converting
to Content-Length. This allows for processing of such requests until
a more permanent solution is developed.

A new configuration option "chunked_transform" has been added to enable
this feature. The option can be set as follows:
  {
    "settings": {
      "chunked_transform": true
    }
  }
By default, this option is set to false, which retains the current
behaviour of rejecting chunked requests with a '411 Length Required'
status code.

Please note that this is an experimental implementation.
