[BI-982] - Ontology BrAPI Mapping for Trait

[dmeidlin]

There is a new trait import template required for changes on the backend:

• "Trait name" is changed to "Ontology term name";
• "Trait level" is changed to "Trait entitiy";
• "Trait attribute" is added.

Should columns such as 'Trait abbreviations' and 'Trait synonyms' be renamed to remove the 'Trait' from the column name? Maybe this is better to be in a different card
