[integration-cli] fix flaky raft test

Browse source 
Fixes previously flaky TestAPISwarmRaftQuorum.

In the test we are shutting down 2 of 3 nodes, all of which are managers.
When this happens the remaining node prepares to step down from being
a leader because there is no longer an active quorum. This test was
written before that change was implemented, and assumes that the
remaining node can still handle requests to create a service (it can't)

There was further flakiness depending on whether or not the node has
stepped down or was in the process of doing so. Fix this by waiting
for the node to completely step down and checking to see if it errors
out like it should.
