Generate a first manual page

Starting from the README of kmf-media-connector,
convert it into rst and add it here.

make man will generate in build/man two man pages:
a big one that is the whole documentation and one
for the kmf-media-connector server.
make text will generate a pure text version of the
tool README in
build/text/components/servers/kmf-media-connector.txt
