Change subject: IMPALA-14493: Cap memory usage of global admission service
......................................................................
Patch Set 1:
Thanks for the review. The major memory usage for admissiond can be for
deserializing the sidecar stuff to read and hold like below. This seems to be
related to IMPALA-14499, as the memory tracker doesn't function correctly in
admissiond. Using tcmalloc stats as a cap is a simpler and safer way to prevent
OOM errors for now.
