Taxonomy2: Update reference to GRIN Taxonomy

The references to GRIN taxonomy grinTaxonomySpecies (and its current variant currentTaxonomySpecies) are automatically detected with the Taxonomy2GRINMatcher.

The detection method is not 100% accurate and may not always detect a matching GRIN record or an incorrect one is assigned.

The UI changes are described in genesys-ui#733 (closed)

• Add FilteredPage<TaxonomySpecies> listSpecies(TaxonomySpeciesFilter filter, Pagination.. method at /taxonomy/grin-species to the Taxonomy controller
• Add Taxonomy2 setGrinSpecies(long taxonomy2Id, Long customGrinSpecies) method at /taxonomy/set-grin-species

class TaxonomySpeciesFilter {
 String _text;
 Set<String> genus;
 Set<String> species;
 StringFilter subtaxa;  
}

The setGrinSpecies() method in the TaxonomyService will:

1. if grinSpeciesId != null, load TaxonomySpecies and set
   1. new property overrideTaxonomySpecies
   2. grinTaxonomySpecies = loaded.id
   3. currentTaxonomySpecies = loaded.currentTaxonomySpecies.id.
2. if grinSpeciesId == null, clear grinTaxonomySpecies, currentTaxonomySpecies and overrideTaxonomySpecies

Update Taxonomy2GRINMatcher

Update Taxonomy2GRINMatcher so that it will use overrideTaxonomySpecies if it is declared.

When the detected TaxonomySpecies.id === overrideTaxonomySpecies.id, then set overrideTaxonomySpecies = null, because now the override is no longer required.

Extended TaxonomyExtraFilter

Update the existing controller endpoint to list Taxonomy2 records with an enhanced TaxonomyFilter with extra options:

class TaxonomyExtraFilter extends TaxonomyFilter {
 Boolean overrides; // if null, ignore. if true, then add `taxonomy2.overrideTaxonomySpecies.notNull()` else `isNull()`
 Boolean grin; // if true, add `taxonomy2.grinTaxonomySpecies.notNull()` else `isNull`
}

The /list endpoint is accessible to all authenticated users.
