Change subject: Enable tcmalloc heap sampling by default ...................................................................... Enable tcmalloc heap sampling by default This enables tcmalloc heap sampling by default with `--heap-sample-every-n-bytes` set to 512KiB. This will allow users to use the `pprof` tool to gather tcmalloc heap profiles from running Kudu processes, at the cost of some overheard in memory allocation. I've been doing a lot of performance testing on a cluster with heap sampling enabled at this frequency and I don't think the overhead is a problem. Enabling this soon after the release of 1.9 gives us lots of time to run this configuration in tests to see if it causes any problems.
