Summary: The current exception string for MapIndexMaxedOut is not very useful because ```oldHashTable.viewWriteHandle()->getKey()``` can have null terminators in it and cause the c_str() to be terminated incorrectly. Regardless, the actual write handle key is not very useful to us. Log the aid explicitly. Example log: ``` Sep 14 07:12:57 tsp_lla/tao/prod-opt-follower/1879 dpdaemon[442]: E0914 07:12:57.836133 1922 Refill.cpp:215] Index has maxed out for key: #1<A4><D1 (https://github.com/facebook/CacheLib/commit/3ec18f5591f75fa5e247cadad19a86126075bdda)>0F<F6>\ ``` Reviewed By: vrishal Differential Revision: D39518530 fbshipit-source-id: 58b9f31f6c0d174d5ec0bc7705788408bc0d11f4
