Description

This affects both Install and Add Host Wizards.
Steps to reproduce:
While installing components, stop the agent on one of the hosts.
Waiting for a while puts the components on the host into the UNKNOWN state.
Click Retry from the UI. This causes a server-side error and the UI gets confused (the hosts are shown with "Waiting" message and no "Retry" button is available).
The user is not able to get out of this state.
