It didn't feel right to have a "DHCPClient" in a "Servers" directory.
Rename this to Services to better reflect the type of programs we'll
be putting in there.
This commit adds a CMakeLists.txt file that will be used by CLion to
configure the project and documentation explaining the steps to follow.
Configuring CLion this way enables important features like code
completion and file search. The configuration isn't perfect. There are
source files for which CLion cannot pick up the headers and asks to
manually include them from certain directories. But for the most part,
it works all right.
