[PATCH core 3/6] Client: Re-use server message for 40x HTTP statuses (DTACLOUD-160)

[mf...@redhat.com]

From: Michal Fojtik <mf...@redhat.com>

Previously the 40x HTTP response status was dropped
and replaced by 'default' description from HTTP specification.
This patch will allow to send user-defined messages from
server. For example code 400 (Bad request) can now indicate
invalid parameters to the client.
