fix(comptaction): use int64_t for parsing total_keys and deleted_keys (#3599)

# Summary 

When the number of total keys is above 2^31 the following error is
present in the logs

```
[E][compaction_checker.cc:87] [compaction checker] Parse total_keys error: out of range of integer type
``` 

Parsing as `int64_t` match `total_keys` and `deleted_keys` type.
