Commit 7a1fe97ae157b19cb19120e26e6a119b4406a893 in impala's branch 
refs/heads/master from Joe McDonnell

IMPALA-13412: Use the BYTES type for tuple cache entries-in-use-bytes

The impala.tuple-cache.entries-in-use-bytes metric currently
uses the UNIT type. This switches it to the BYTES type so that
the entry in the WebUI displays it in a clearer way (e.g. GBs).
This switches impala.codegen-cache.entries-in-use-bytes the same
way.

 - Ran a core job
