KUDU-3557 Simple way to change maximum thread cache size of tcmalloc.

Now, Lock contention is too high in tcmalloc while the cluster in
under high throughput. Making the total thread cache size larger
could highly decrease the lock contention. Even though the max size
of one single thread cache could not be larger than 4096KB, but
thread cache does not need to release the memory to central free
list all the time if max_total_thread_cache_bytes is larger.

KUDU-3557 shows the difference on lock contention while setting
different sizes of max_total_thread_cache_bytes. Please check it
for detail.
