Query for image deletion

[rjschwei]

Our image deletion date is defined as deprecation-date + 6 months. We have a user of the API that is interested in being able to query the expected deletion date. For this we have 2 use cases

1.) Receive a list of all images to be deleted on or before a given date

• The user must be able to filter this result set by framework and region

2.) Get the expected deletion date for a given image name

We identified the follow new V1 API requests:

• /v1/images/deletedby/{date}
• /v1/{provider}/images/deletedby/{date}
• /v1/{provider}/{region}/images/deletedby/{date}
• /v1/{provider}/images/deletiondate/{image}
• /v1/{provider}/{region}/images/deletiondate/{image}

For the provider specific deletedby API requests the result will be a list, possibly empty, of images that will be marked as deleted by the specified date, with the results looking similar to the existing provider image list queries.

For the provider specific deletiondate API requests the result with be a deletion date value, which may be empty if the specified image couldn't be found, or the image is not yet marked as deprecated.

The global images deletedby query is a little different; the result will be a list of providers, and for each provider there will be a potentially empty list of images that will be marked as deleted by the specified date. The XML result of such a query should look similar to:

<providers>
  <provider name="alibaba"/>
  <provider name="amazon"/>
  <provider name="google">
    <images>
      <image deletedon="".../>
      <image deletedon="".../>
    </images>
  </provider>
  <provider name="microsoft">
    <images>
      <image deletedon="".../>
      <image deletedon="".../>
    </images>
  </provider>
  <provider name="oracle"/>
</providers>

Changes landed in #123 implement the provider specific deletedby and deletiondate requests.

The global deletedby request will be implemented in a follow on submission.
