Aliaksandr Valialkin faf07fbc67 lib/bytesutil: optimize internStringMap cleanup
- Make it in a separate goroutine, so it doesn't slow down regular intern() calls.

- Do not lock internStringMap.mutableLock during the cleanup routine, since now
  it is called from a single goroutine and reads only the readonly part of the internStringMap.
  This should prevent from locking regular intern() calls for new strings during cleanups.

- Add jitter to the cleanup interval in order to prevent from synchornous increase in resource usage
  during cleanups.

- Run the cleanup twice per -internStringCacheExpireDuration . This should save 30% CPU time spent
  on cleanup comparing to the previous code, which was running the cleanup 3 times per -internStringCacheExpireDuration .
