Previously, breakpoints were not removed when an update operation failed. If a user ran the "openstack overcloud update" command and it failed, it is possible that the subsequent stack-update command (e.g. "openstack overcloud deploy") might be stuck in the 'IN_PROGRESS' state waiting for the removal of breakpoints.
With this update, all existing CLI commands explicitly remove any existing breakpoints when running a stack-update operation. As a result, the stack-update operations do not get stuck in the 'IN_PROGRESS' state while waiting for the breakpoint removal.
