Update the Ironic core team list

Update the Ironic core team list.

Sean and Mikal were removed a while back, but I forgot to update this
list. Roman and Max were added last week.

Change-Id: I54858324b46dcbb69a259391c4cbc6b8a0c942e5
Add Sergey Lukjanov to infra-core

Change-Id: Ie7fc10f6024b90675e92d15fd4fd3a6b8c5e81ef
Add new infra projects

The minor reordering is to match what is returned by gerrit from
ls-projects.
