Please help review the patch. It mainly includes an attribute named
"model_version" in RootPersistentEntity and the value will come from
org.apache.kylin.common.KylinVersion.CURRENT_KYLIN_VERSION by default and will
be filled by calling RootPersistentEntity.updateVersionAndRandomUuid while
creating new persistence entities.
Sample metadata:
{code}
{
uuid: "dcea60b8-caf9-45d8-98af-909f0c3d842d",
name: "tutorial",
tables: [
"EDW.TEST_CAL_DT",
"EDW.TEST_SELLER_TYPE_DIM",
"EDW.TEST_SITES"
],
owner: "ADMIN",
status: "ENABLED",
description: "The tutorial cube project.",
models: [ ],
last_modified: 1454086485867,
model_version: "2.1",
create_time_utc: 1454086358800,
last_update_time: null,
realizations: [ ]
}
{code}
The only concern here I think is the version attribute name, I thought to use
'version' but the `CubeInstance` has version attribute already, so I have to
use 'model_version', how do you think about ?

> Currently metadata does not have special property to identify its version,
> even though we already versions of metadata in 1.x, 2.0 and 2.x. If each file
> in the metadata is bound with version it will be easier for upgrading related
> issues.
