Public bug reported:

The DB query for flavor extra-specs is case-insensitive, but the code to
handle update vs. create is case-sensitive.  This causes unexpected
behavior when trying to "fix" case on extra-specs:

Steps to reproduce:

    Stand up a devstack with the MySQL backend.

    nova flavor-key set 1 aaa=haha
    nova flavor-key set 1 AAA=lolz

Expected results:

Option 1: Two extra specs, named "aaa" and "AAA", with distinct values

Option 2: The extra spec named "aaa" replaced with "AAA"

Actual results:

a 409 Error from the client, and an exception throwing the exception on
the backend
