TT#45715 accounting.cdr_export_status tables

- currenty, there is only cdr.export_status and cdr.exported_at columns
to mark rows already written.
- to handle the AMA ticket export (and other exporters in the future), a
table "accounting.cdr_export_status" is introduced, defineing "streams".
for now there will be "defualt" (the good old cdr-exporter) and
"ama-simples" (for UPC AT)
- the table accounting.cdr_export_status_data stores individual vlaus
for "export_status" (unexported, ok, failed) and exported_at timestamp
per cdr and per cdr exort stream

- all cdr relation table triggers for emulating fk are refactored to be fast.
