**Current behavior :
For queries such as 1 - sum(foo), when local shards are unhealthy, the HighAvailabilityPlanner will create a remote plan 1 - sum(foo) that runs in its healthy buddy cluster. This, however, cause that the query behaves equivalent to 1 - Remote(1 - sum(foo)).
New behavior :
The same query will be materialized something like1 - Remote(sum(foo)) to produce the correct result.
