This commit removes the 5.4-to-6.0 upgrade guide and all references to it.
It mainly removes references to the Enable Consistent Topology Updates page,
which was added as enabling the feature was optional.
In rare cases, when a reference to that page is necessary,
the internal link is replaced with an external link to version 6.0.
Especially the Handling Cluster Membership Change Failures page was modified
for troubleshooting purposes rather than removed.
This doesn't apply for auth-v2 as we improved data placement and
removed cassandra quirk which was setting different CL for some
default superuser involved operations.
Fixes#18773Closesscylladb/scylladb#18785
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.

Fixes https://github.com/scylladb/scylla-docs/issues/4028
The goal of this update is to discourage the use of
the default cassandra superuser in favor of a custom
super user - and explain why it's a good practice.
The scope of this commit:
- Adding a new page on creating a custom superuser.
The page collects and clarifies the information
about the cassandra superuser from other pages.
- Remove the (incomplete) information about
superuser from the Authorization and Authentication
pages, and add the link to the new page instead.
Additionaly, this update will result in better
searchability and ensures language clarity.
Closes#14829
Since repair is performed on all nodes, each node can just repair the
primary ranges instead of all owned ranges. This avoids repair ranges
more than once.
Closes#14766
