Mariadb does not accept _prefixed fields by spec, and these columns may give future issues. Migrate all fields in installer to remove this prefix (without data loss) and:
Create new view sccplineconfig for chan-sccp where only accepted fields are shown
Update sccpdeviceconfig to only show accepted fields
Update extconfigs.conf to use sccplineconfig
Remove references to _ prefixed fields
chan-sccp has parsable fields where two values are separated by a |.
Parse these fields and their associated values and create two fields.
Remove the unparsed field if it exists.
