This commit excludes OSS-specific links and content
added in https://github.com/scylladb/scylladb/pull/17624
to separate files and adds the include directive `.. scylladb_include_flag::`
to include these files in the doc source files.
Reason: Adding the link to the Open Source upgrade guide
(/upgrade/upgrade-opensource/upgrade-guide-from-5.4-to-6.0/enable-consistent-topology)
breaks the Enterprise documentation because the Enterprise docs don't
contain that upgrade guide. We must add separate files for OSS and
Enterprise to prevent failing the Enterprise build and breaking the
links.

This commit includes updates related to replacing system_auth with system_auth_v2.
- The keyspace name system_auth is renamed to system_auth_v2.
- The procedures are updated to account for system_auth_v2.
- No longer required system_auth RF changes are removed from procedures.
- The information is added that if the consistent topology updates feature
was not enabled upon upgrade from 5.4, there are limitations or additional
steps to do (depending on the procedure).
The files with that kind of information are to be found in _common folders
and included as needed.
- The upgrade guide has been updated to reflect system_auth_v2 and related impacts.
