Support sort parameter when listing extensions

[JohnNiang]

What type of PR is this?

/kind feature
/area core

What this PR does / why we need it:

Currently, we cannot pass a sort parameter into extensions' list API, so the result of the API is unsortable.

This PR add the support for that API. e.g.:

curl -X 'GET' \
  'http://localhost:8090/api/v1alpha1/annotationsettings?sort=metadata.name,desc' \
  -H 'accept: */*'

Does this PR introduce a user-facing change?

Extension 查询接口支持排序参数。
