Remove Ed as Maintainer

Ed is no longer working on the OpenBMC project.
https://lists.ozlabs.org/pipermail/openbmc/2019-October/019000.html

During Ed's time as a Maintainer, the Web UI moved from a prototype,
that could only be run locally to a full-fledged ~20 page Web
Interface with features such as Serial Over Lan Console, IP KVM,
Virtual Media, LDAP, and Multiple User Mangement, that takes up
only ~450KB in the build.
