New description:

 When a core auto-update fails, core has long had the ability to
 automatically attempt a "rollback" to the latest stable release (in the
 branch that the site is running).  Note: for core auto-updates, "rollback"
 is not attempted for certain failures (e.g. "disk full", etc).

 This capability should be extended to be available for plugin and theme
 updates.

 [note: originally this description mentioned `auto-updates`...that was a
 mistake on my part.  This is about rollback for both `manual` and `auto-
 updates`]

 The current functionality for core rollbacks relies on the availability of
 a "rollback" package being returned by the Updates API.  It is unclear (to
 me, at this time) whether extending this functionality to plugins/themes
 will require changes to the API or not.

 **Important:** This ticket is **not** about backup/restore in case a site
 admin later determines that a `successful` plugin/theme update actually
 causes problem on a site!!!!  Rather it is about covering cases such as
 #51823, where a plugin/theme update failure happens between the time the
 existing plugin/theme is deleted but before the new version successfully
 installed.
