If batch updating fails in a pool, this code will do the clean up by
running the appropriate (next in the queue) RemoveUpdateFilesFromMaster action. In addition to Pool_update.clean(), Pool_update.destroy() will be called when needed.

XenCenter will check host.patches_requiring_reboot when a host restart is due while a batch update is in progress. If the restart is not required, XenCenter will skip relevant PlanActions.
The intention here is to check this whenever a restart is due according to the original schedule - this way a completely livepatchable update can prevent the restart while the key batch hotfixing logic is not changed.

The PatchPrechecksOnMultipleHostsInAPoolPlanAction did not filter the patchmappings by masterhost, so with some probability, it could choose the wrong mapping (pool_patch object for the same update, but in different pool). This bug is being fixed in this commit, other changes only renamed (for more consistent naming) a class and removed an unused field.

Where (in code removed by this commit) we iterated through the planActionsByHost dictionary, the hosts were iterated through in the order how the dictionary was initialized. Despite the actions were added in the right order, they then were screwed up, because the Cache.Hosts can have the hosts randomly while we want the master to be first.
To fix the bug, I changed the data structure from a dictionary to a list that has the actions exactly in the (good) order, the order they were added, eliminating the risk of the actions being retrieved in the wrong order.

Fixed display issue, now showing pools (and standalone hosts at the same level), not masters.

Implemented error handling.
If there has been an error in a pool, we stop executing actions in that pool immediately, and report the error once every other actions have finished. Error in one pool will not affect the upgrade process of other pools.
