Create API GET/data-export/logs/{jobExecutionID} for error log handling

Purpose/Overview:
Create API so that UI can retrieve error log and render it to the user.

Requirements/Scope:
1. Errors should be grouped by export job id
2. Errors should contain following elements:

• date, time
• log level (set to ERROR in Q3)
• reason
• affected record - if applicable

Additional information:
1.Type of errors tracked:

• Underlying data (missing required data, invalid/duplicate keys, null or empty values, too long/large values)
• Connectivity issue (no response from db, S3)
• Creating export file (Storage space)
• Reading input file (UUID not found, invalid data, cannot find the file for reading, file not found)
• Mappings (null or empty, too long/large value, unsupported mapping)

2. Details of affected records are tracked in MDEXP-257 (Instances), MDEXP-259 (Holdings), MDEXP-260 (Items)

Approach:
Create an API GET/data-export/logs/

. Come up with a schema to handle all the above types of errors.

Acceptance criteria:

• Come up with the schema to handle all the above scenarios
• API is created
• Unit and API tests are written
