Fix race in TestApiSwarmRestartCluster

Browse source 
In `TestApiSwarmRestartCluster`, it's calling `checkClusterHealth`.
`checkClusterHealth` calls `d.info()`, which will return an error if
there is no cluster leader... problem is `checkClusterHealth` is doing a
nil error assertion w/o giving any time for a leader to be elected.

This moves the `d.info()` call into a `waitAndAssert` using the default
reconciliation timeout.

It also moves some other checks into a `waitAndAssert` to give the
cluster enough time to come back up.
