[discuss] add custom extension fields to route, server, and upstream objects.

[YuanSheng Wang <me...@apache.org>]

These objects of APISIX may be managed by a third-party platform, adding
custom extension fields to
allow the third-party management platform to store some personalized data
items.

the `extension` is the new field.

```
{
    "uri": "/index.html",
    "upstream": {
        ... ...
    },
    "extension" {
        ... ... # allow user to define
    }
}'
```

Hi YuanSheng.
I think the ETCD data should be hidden for users.
and Can you come up with a scenario or example how user can use this
extension field?

Hi, yuansheng,
What data items will stored in this `extension` filed? Can you show same
examples?
And how to limit the size of `extension`? Is user can write large data to
crash etcd?
