In test_disagg_failover_perf.cpp

We have the line: 

if (opt.warm_cache_pct > 0)
     cache_warming(opt.collection_count  ** opt.key_count  ** opt.warm_cache_pct / 100);
To avoid overflow, we should cast to int64_t 

Unintentional integer overflow

The expression's value may not be what the programmer intended, because the expression is evaluated using a narrow (i.e. few bits) integer type. An integer overflow occurs, with the result converted to a wider integer type
/test/cppsuite/tests/test_disagg_failover_perf.cpp:581: OVERFLOW_BEFORE_WIDEN 184231 Potentially overflowing expression "opt.collection_count * opt.key_count" with type "int" (32 bits, signed) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "int64_t" (64 bits, signed).
