Summary:
Simple component that will add a new entry in a log file every time we lookup/insert a key in SimCache.
API:
```
SimCache::StartActivityLogging(<file_name>, <env>, <optional_max_size>)
SimCache::StopActivityLogging()
```
Sending for review, Still need to add more comments.
I was thinking about a better approach, but I ended up deciding I will use a mutex to sync the writes to the file, since this feature should not be heavily used and only used to collect info that will be analyzed offline. I think it's okay to hold the mutex every time we lookup/add to the SimCache.

Summary: This uses `clang-tidy` to comment out unused parameters (in functions, methods and lambdas) in fbcode. Cases that the tool failed to handle are fixed manually.
