fix(scs_it4i): use send_lib.py, support v2 API
Created by: zlamalp
- Service endpoint uses new version of API.
- Updated object param names (use underscores instead of came-case).
- Pass "einfra" login as "login" param.
- Pass "einfraid-persistent" login as "id" param.
- Switch to using send_lib.py where possible instead of custom code.
- Temporary switch to pytho3.11.
- Fixed passing JSON to the request.
