Kea1.5-beta1

Objectives of this milestone are:

YANG/NETCONF - an ability for Kea to be able to store major parts of its configuration as YANG configuration and be able to manipulate it using NETCONF interface
Better congestion handling - Kea 1.4 does not behave well if there's more traffic it can handle. This new feature will improve the situation.
Global host reservations - reservations that could be used in any subnet.
A design for Config Backend - an ability to store major elements, such as subnets, pools and shared networks in a database. We plan to do a design and some preparatory foundation code in 1.5, with the actual complete implementation to follow up in 1.6
User contexts in leases - ability to add and keep user information in leases
REST API documentation - we now have a much cleaner REST API documentation
Class commands - a new hook that allows to manage client classes on the fly, without restarting the server or going through the whole reconfiguration process.

Due date is tentative and subject to change.
