Daryn Sharp updated YARN-6679:
    Attachment: YARN-6679.2.trunk.patch

[~daniel@cloudera.com], I'll save my get out of jail free card.  I added tests that new instances
are not pb impls and the to/from conversion is correct.  {{TestPBImplRecords}} also already
does pb conversion tests so coverage should be good.

> Creating and using transient PB-based Resource instances during scheduling is very expensive.
 The overhead can be transparently reduced by internally using lightweight non-PB based instances.
