This commit does 2 changes in the OIDC app docs:
1) The docs were updated to be explicit about the OIDC app being
compatible with LDAP servers and not only with the Windows Active
Directory;
2) The page "Centralized OIDC Authentication Setup for Distributed
Cloud" was renamed to "Centralized vs Distributed OIDC Authentication
Setup" and was moved in the index of pages to be right below the
first page "Overview of LDAP Servers". The idea is to use this page
as a entry point for someone learning about the OIDC app, because
every user must decide between a centralized and a distributed setup
and because this page has links to all other pages except
"Deprovision LDAP Server Authentication".
