   If create tablet thread blocked by report thread, they are mutually exclusive.
   
   This PR may cause the following case:
   1. Report thread begin collect tablet info, now report version is v1.
   2. Create thread create tablet X, and change the report version to v2.
   3. Report thread ends collecting tablet info without X and report all tablet info to FE.
   4. FE receive tablet info without X and delete X from meta.
   
   I modified the behavior of tablet report. Before collecting tablet information, mark the report version. After the collection, compare the current report version with the version just marked, if the version has changed, then abandon this report.
