[BI-1570] - Improve error reporting - Text to Table

[HMS17]

Description

Story: BI-1570 - Improve error reporting - Text to Table

Added ImportError class to handle previously in a list errors for import, and utilized it to display import errors in a sortable table.

Dependencies

bi-api/develop

Testing

For Germplasm, Ontology, and Experiment Import:

• Import file that before now would give row errors, ie:
  -- Germplasm - invalid breeding methods, required field with empty values
  -- Ontology - Missing scale categories for nominal/ordinal scale, missing required fields, trait name duplicate,
  -- Experiment - Non-existing GID
• See that errors now display in table
• Check that table columns are sortable

(NOTE that frontend showAll is broken and will be resolved in another card)
