Glance API support for “multipart/form-data” contentType

Registered by Yehia Beyh

Adding or modifying an image metadata using the Glance API/API is done by specifying the metadata in the HTTP headers that begins with the prefix “x-image-meta-“. Some internet browsers such as Internet Explorer ignore the HTTP headers thus making it impossible to upload an image and set the metadata on the image successfully.

In addition, the _upload function in api/v#/images.py only supports “application/octet-stream” contentType. In order to overcome this limitation, we propose support for “multipart/form-data” contentType. Given a response and mapping of image metadata, injects the Response with a set of HTTP headers for the image metadata. Each main image metadata field is injected as a HTTP header with key 'x-image-meta-<FIELD>' except for the properties field, which is further broken out into a set of 'x-image-meta-property-<KEY>' headers.

Whiteboard

It looks like multipart/form data is just another way to encode/send http headers, so this should be a pretty non-disruptive change

Looks like maybe folks are okay with just using v2 for this use case--which is fine. I think there is also room to implement support for it in v1 as an optional middleware. But since it seems like interest has dropped off I'm removing this from the list for now. (markwash)
