WIP: Update list of supported (i.e. deprecated) hypervisors and OS-es for 4.14 (#96)

* update-deprecated-hypervisors-and-os

THIS NEEDS REVIEW - we had a discussion (i.e. nothing is really yet removed from the code base, or very few things) - but we don't build packages for CentOS 6 any more, nor are we testing with ancient hypervisors versions (VMware =< 5.5, XenServer =< 7.1, Ubuntu =<14.04)

* typos and formatting
