> When creating an upgrade on a large cluster, the backend currently takes a very long
time to create the data and persist it. Although steps are being taken to greatly reduce this
time, it could still take up to several minutes for this request to go through.
> The web client currently doesn't wait long enough for the upgrade to being. It will produce
an error message saying that the upgrade could not be created and then gets confused when
the upgrade eventually shows up. It also allows a user to try to create another upgrade while
the first is still being generated.
> STR:
> - Create a rolling upgrade on a cluster with 1000 hosts where every host has 15 components
installed.
