With TTL based discarding and upcoming lease extension, remote cache eviction error won't happen if remote cache can guarantee the TTL. However, if it happens, it usually means the remote cache is under high load and it could possibly evict more blobs that Bazel wouldn't aware of. Following builds could still fail for the same error (caused by different blobs). This PR changes to remove all remote metadata when the remove cache eviction error happens (which should be rare with the help from TTL based discarding and lease extension) to make sure next incremental build can success. Part of bazelbuild#16660. Closes bazelbuild#17747. PiperOrigin-RevId: 516519657 Change-Id: Ia99770b9d314ca62801b73dc96d09ed8ac2233f6
