[QA] Make logging faster on startup

[romtsn]

📜 Description

• There are some benchmarks in here comparing String.format vs plus-operator, and String.format is indeed slower.
  • Since we're doing some logging on startup (e.g. when parsing the manifest), even when debug is set to false, this was adding some overhead. I've removed the redundant log call + add changed String.format usages to the plus operator
• We were doing unnecessary String.format even when there are no args passed, so we check for their presence now and call the method without String.format explicitly now
