Subject: [PATCH] Fix Missing IgnoredUnavailable Flag in 7.x SLM Retention Task
 (#56616)

Without the flag we run into the situation where a broken repository (broken by some old 6.x
version of ES that is missing some snap-${uuid}.dat blobs fails to run the SLM retention task
since it always errors out).
