Our manuals explain that the cs7 config automatically adds missing parts.
However, previous code requires an ASP to exactly match the default name that
the autoconfiguration would choose -- that is unintuitive.
If a config included only an ASP, or both AS and ASP but omitting to add the
ASP to the AS, auto configuration would pick it up iff it exactly had the name
the application chose. For osmo-bsc, that was 'asp-clnt-msc-0', if 'msc 0' is
the first MSC in the config file. For osmo-msc, it is 'asp-clnt-OsmoMSC-A' or
'asp-clnt-OsmoMSC-A-Iu' and so forth, so it is not always clear which name the
user should pick to get the ASP used by auto config.
Refactor so that any ASP with a matching protocol that is not associated with
any AS yet is picked up by the auto configuration, i.e. associated with the AS
etc., regardless of the name chosen in the config file.
