Drop support for signing rpm-wrapped artifacts

This was only usable in live_images phase that doesn't exist anymore,
and wasn't used much in the first place.

-Signing
-=======
-
-If you want to sign deliverables generated during pungi run like RPM wrapped
-images. You must provide few configuration options:
-
-**signing_command** [optional]
-    (*str*) -- Command that will be run with a koji build as a single
-    argument. This command must not require any user interaction.
-    If you need to pass a password for a signing key to the command,
-    do this via command line option of the command and use string
-    formatting syntax ``%(signing_key_password)s``.
-    (See **signing_key_password_file**).
-
-**signing_key_id** [optional]
-    (*str*) -- ID of the key that will be used for the signing.
-    This ID will be used when crafting koji paths to signed files
-    (``kojipkgs.fedoraproject.org/packages/NAME/VER/REL/data/signed/KEYID/..``).
-
-**signing_key_password_file** [optional]
-    (*str*) -- Path to a file with password that will be formatted
-    into **signing_command** string via ``%(signing_key_password)s``
-    string format syntax (if used).
-    Because pungi config is usually stored in git and is part of compose
-    logs we don't want password to be included directly in the config.
-    Note: If ``-`` string is used instead of a filename, then you will be asked
-    for the password interactivelly right after pungi starts.
