[catenacyber]

Link to redmine ticket:
None, preliminary work for https://redmine.openinfosecfoundation.org/issues/5053 and app-layer plugins
Continuation of #8772

Describe changes:

• Fix setup-app-layer script so that it adds app-layer metadata to alerts
• Adds ftp metadata to alerts
• Adds tftp metadata to alerts
• Adds krb5 metadata to alerts

Continues #8864 by incorporating more protocols : Mqtt, rfb, snmp and krb5 (which was not there before)

SV_BRANCH=pr/1196

OISF/suricata-verify#1196

Still to do :

• finish to list remaining protocols
• Create tickets for missing protocols : pgsql, dcerpc, dhcp,
• A next iteration can have JsonGenericLogger to replace all JsonBitTorrentDHTLogger and remove output-json-bittorrent-dht.c
