issue: #42942 This pr includes the following changes: 1. Added checks for index checker in querycoord to generate drop index tasks 2. Added drop index interface to querynode 3. To avoid search failure after dropping the index, the querynode allows the use of lazy mode (warmup=disable) to load raw data even when indexes contain raw data. 4. In segcore, loading the index no longer deletes raw data; instead, it evicts it. 5. In expr, the index is pinned to prevent concurrent errors. --------- Signed-off-by: sunby <sunbingyi1992@gmail.com>
