a tool for preparing build environment, building and unittesting Kea

Here's Michał's description:

The aim of this tool is in vanilla environment setting up Kea build dependencies and performing a build and unit tests.

The build can be executed in 3 environments: local system, VirtualBox and LXC.

I wanted to solved a problem of dealing with rather complicated set of deps that we have and also with configuring and building procedure. Currently the tool is able to execute a build on all supported systems in one command line invocation which I think is pretty nice for new comers or people who deal with particular systems not that often. The target users of the tools are Kea developers and CI system on Jenkins.
