Let's set Cache-Control to no-store if there were any warnings while
the query was being executed i.e. it is a partial response or we got
some other problem.

Seems like this works successfully in tandem with cortexproject/cortex#1974.

Tested by turning off one sidecar which leads to warnings and then Cortex Query Frontend did not save anything into the cache when querying.
