This updates links to slapos.git in the tree to point to new location.
We do so whole-tree except one place in stack/monitor/ :
recipe = hexagonit.recipe.download
url = http://git.erp5.org/gitweb/slapos.git/snapshot/930be99041ea26b7b1186830e5eb56ef0acc1bdf.tar.gz
(see d8800c0b "monitor: Download statics files from snapshot")
The reason we do not update that link yet, is that 930be99041ea26b7b1186830e5eb56ef0acc1bdf
is a tree object and gitlab does not allow to dowload tree object as archives (yet ?)
So for now that link stays unconverted - and we'll think how to do with it.
