Drop Django based implementation of launch instance

horizon already deprecated launch instance Django based implementation
in the wallaby cycle [1]. This patch remove code for launch instance
Django based implementation as angular based implementation is the
default one from long and all features gaps between angular and Django
implementation is closed.

It also moves SetAdvanced step code to ``resize_instance.py`` as
``workflows/create_instance.py`` file is deleted and remove server_group
option from Advanced Options of resizing instance action because
"server_group" is not required while resizing an instance as per
nova-api reference [2].

Closes-Bug: #1869222
