The biggest change is that the upgrade_groups() is a list of tuples ... [()] ... rathern than a collections.OrderedDict(). This tends to make more sense as they are processed in order and don't actually need to be indexed. Also excludes easyrsa (as it's not an upgrade target) and adds a "Database Services" which upgrades mysql or percona FIRST before moving on to rabbitmq and other stateful services. This is because some charms really need to talk to mysql if one of the other stateful services does a relation changed hook. This makes it more likely that the system will ugprade correctly.
