Hi all,

Following up to the previous mailing list [1] and virtual meetup [2]
discussions, I would like to announce the plans to deprecate the 'iscsi'
deploy interface.

This is the updated plan discussed on the virtual meetup:
1) In the Victoria cycle (i.e. right now):
  - Fill in the detected feature gaps [3].
  - Switch off the iscsi deploy interface by default.
  - Change [agent]image_dowload_source to HTTP by default.
  - Give the direct deploy a higher priority, so that it's used by default
unless disabled.
  - Mark it as deprecated in the code (causing warnings when enabled).
  - Release a major version of ironic to highlight the defaults changes.
2) In the W cycle:
  - Keep the iscsi deploy deprecated.
  - Listen to operators' feedback.
3) In the X cycle
  - Remove the iscsi deploy completely from ironic and IPA.
  - Remove support code from ironic-lib with a major version bump.

Please let us know if you have any questions or concerns.
