doc: Remove mentions of server-side CRL and CA file names

Commit a445cb9 removed the default file
names for server-side CRL and CA files, but left them in the docs with a
small note.  This removes the note and the previous default names to
clarify, as well as changes mentions of the file names to make it
clearer that they are configurable.
