CRUD operations support for EDIFACT records

Steps:

• define "MARC" default value for the "recordType" query parameter of get /source-storage/source-records endpoint
• add "recordType" query parameter for get /source-storage/records endpoint with default value "MARC"
• extend RecordType enum with EDIFACT value and "edifact_records_lb" table name
• review and update records related persistence layer components to support CRUD operations for EDIFACT records (use "recordType" query parameter and RecordType enum to determine the corresponding record parsed content table (marc_records_lb/edifact_records_lb)
• add tests
