Changes

filters/auth: release tokeninfo cache mutex earlier (#3241)

  • filters/auth: reset parallelism for BenchmarkTokeninfoCache

  • filters/auth: release tokeninfo cache mutex earlier

Cached value is readonly so release cache mutex early to
copy and adjust cached value outside of critical section.
