["Lars Volker (Code Review)" <ge...@cloudera.org>]

Hello Tim Armstrong, Impala Public Jenkins, 

I'd like you to reexamine a change. Please visit

    http://gerrit.cloudera.org:8080/12543

IMPALA-8234: Fix ordering of Thrift enum, fix enum values, add warning

IMPALA-7694 added a field in the middle of the Metrics.TUnit enum, which
broke backwards compatibility with profiles that had been written by
older versions of Impala. This change fixes the ordering by moving the
field to the end of the enum.

Additionally, it adds a warning to the top of all Thrift files that are
part of the binary profile format, and an note of caution to the main
definition in RuntimeProfile.thrift.

This change also fixes the order of all enums in our Thrift files to
make errors like this less likely in the future.
