Hello Yair Zaslavsky,
I'd like you to do a code review. Please visit
http://gerrit.ovirt.org/21305
to review the following change.
Change subject: core: Adding JsonPropertyRename
......................................................................
core: Adding JsonPropertyRename
Adding the JsonPropertyRename annotation
which can be set on a Mixin setter method.
This annotation means that the the field got
changed from a previous version, so it should be
looked up at the Deserialization resolver, and be
translated to the field as existed at the time
the payload was serialized.
