What Does This Do

Caching the primaryInstrumentationName to avoid repeatedly calling instrumentationNames and constantly allocating a String[]

Motivation

Avoid repetitive work and memory allocation

Additional Notes

The high load benchmarks are known to be flaky, but I wanted to double check the regressions anyway.
In a local load test, this change performed as expected...

  • equal to master on Spring PetClinic 64MiB heap
  • slightly than master on Spring PetClinic 256 MiB heap
