Move the access control from the Cypher manual (#1047) (#1140)

Most of the Access control pages have been moved straightforwardly. The
pages that need a review are the following:

- modules/ROOT/pages/authentication-authorization/index.adoc --> It
contains the content from

https://neo4j.com/docs/cypher-manual/current/administration/access-control/,
which has been rewritten and merged into

https://neo4j.com/docs/operations-manual/current/authentication-authorization/introduction/.

- _Manage privileges_ has been renamed to _Manage privileges for RBAC
and fine-grained security_ to avoid duplication with the title of the
parent section.

-

https://neo4j.com/docs/cypher-manual/current/administration/access-control/built-in-roles/
is the same; it just starts with the content from

https://neo4j.com/docs/operations-manual/current/authentication-authorization/built-in-roles/

- I turned the
https://neo4j.com/docs/operations-manual/current/authentication-authorization/terminology/
into a section on the top page, _Authentication and authorization. -

https://neo4j.com/docs/operations-manual/current/authentication-authorization/access-control/
has been renamed _Fine-grained access control (example)_ and now lives
under _Tutorials and examples_.
