[api] Add metrics to api tester (#9307)

This commit introduces logging tools on top of the consistent API testing introduced here. See proposal for more high level information.

Changes:

Added metrics pusher to aptos-api-tester with 4 histogram metrics for success, error, fail rates, and latency.
Added logs to tests instead of printing to stdout.
