BRS-357: Separate each variance into individual cells, increase export timeouts

[davidclaveau]

Ticket:

#357

Description:

• Update the Variance Report Export to contain columns for each variance report item

  • Take the items in EXPORT_VARIANCE_CONFIG and flatten the keys into an array
  • Use the flattened array to compare against the record.fields, which are the variance items found in each record
  • If the key matches a field, then we push the key to the record under their own item record[field.key] (as opposed to daisy chaining all the variances under fields).

• Also, increase timeout for the exporter to fix issue from #291 as they seem to take a little longer with the V3 SDK in prod

• Linting fixes to test files and template.yaml
