  - Merge "Doc: remoteNameStyle might result in a repo name clashes" into stable-3.2
  - Doc: make explicit that remoteNameStyle is for non-Gerrit repos
    
    The documentation already specify non-Gerrit examples of use
    of remoteNameStyle; however, it does not say that if the remote
    repository is backed by Gerrit, the *ONLY* supported option is
    "slashes", otherwise the consequences could be catastrophic.
    
    Two Gerrit servers (e.g. primary and replica) need to have
    full alignment of repository names, as they are also referenced
    in the inherited ACLs. Having a repository name mapping, may
    disrupt the ACLs evaluation and make the remote Gerrit replica
    unusable.

  - Doc: remoteNameStyle might result in a repo name clashes
    
    When using the remoteNameStyle in the replication.config settings
    the Gerrit admin needs to be warned on the risks of using sytles
    that may be ambiguous and associate two source repositories to
    the same target repository on the replica.
    
    Example: set remoteNameStyle to basenameOnly
    
    /foo/my-repo.git => pushed to my-repo
    /bar/my-repo.git => pushed to my-repo
    
    When two commits are pushed to the same branch on the two repos
    /foo/my-repo.git and /bar/my-repo.git, the replication plugin
    would push them to the same target repo my-repo, causing clashes
    and losing commits (depending which one is pushed first).
    
    The risk needs to be highlighted so that the Gerrit admin
    can check that univocity of the mapping is respected.
