Middle-East to esams

Switch Middle-East to esams as it's likely to be much better connected
there than eqiad. A few countries were already there and others are
included from more other places in the hierarchy (Turkey is under EU and
already pointed to esams, Egypt is under Africa and pointed to esams by
previous commit etc.)
