Accession similarity search

grin-global/grin-global-ui!391 requires API support to find similar Accessions in the database using the existing DuplicateFinder base implementation.

After implementing the AccessionDuplicateFinder component, add the following endpoints to AccessionController:

POST /a/similar public List<DuplicateFinder.Hit<Accession>> findSimilarForUnsaved(@RequestBody(required = true) final Accession source)

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
