Indicate the current leader in status output

[Mark Shuttleworth]

Please show the leader unit in the default status UNIT table, using an asterisk appended to the UNIT column:

UNIT
elasticsearch/0*
elasticsearch/1
etcd/0*
  filebeat/0*
  topbeat/0
etcd/1
etcd/2
  filebeat/1
  topbeat/1*
kibana/0*
kubernetes/0*
kubernetes/1
kubernetes/2

Thanks!

Do we really want it on every unit even if there is only one instance for an application?

The problem with not doing it on the single-unit ones is that it turns
the leader indication into a surprise later. And the problem with
tagging it onto the end of every unit name is it makes the simple case
harder to read. I didn't want to have a whole column just for this,
though (the name of the column would be much longer than the content
:)). We already have the "Messages" column but I don't see a nice way to
add it there.

For now, I think we should show it for all applications in the tabular output, even when there is only one unit for an application.
