As discussed in the horizon meetings or in horizon PTG sessions, horizon team agreed to deprecate django version of Images, Keypair and Roles panel as we think that feature gaps between the two implementations have been closed. Let's mark the Django version as deprecated for all these panels and gather more attention from operators. Change-Id: I965f9dbdd5e78b52a788f73b359c1c6fbc18637e
