[BUG] Rollovering aliases should support remote snapshot index

[kkewwei]

Describe the bug

Same as #11226, we use alias to rollover the index, and restore the index as a searchable snapshot index, the restored searchable snapshot index is read-only, and share the same alias with the rollover index. But rollover operation will check the indices using the alias, and is blocked by METADATA_WRITE,

[FORBIDDEN/13/remote index is read-only];index [remote-index1-000006] blocked by: [FORBIDDEN/13/remote index is read-only];index [remote-index1-000001] blocked by: [FORBIDDEN/13/remote index is read-only];index [remote-index1-000002] blocked by: [FORBIDDEN/13/remote index is read-only];

2. rollover POST nginxlogs/_rollover

3. set the first index read-only

   PUT nginxlogs-000001/_settings
   {
   "index": {
       "blocks.read_only":"true"
   }
   }

4. rollover and throw exception.
