add endpoint for querying GFE based on an IPD allele input

[rsajulga-nmdp]

Given an input IPD-IMGT/HLA Allele, what is its GFE and what are its features (ordered)?

In the future, ideally the ordering of features (5'UTR - exons,introns - 3'UTR) would be embedded within the database so that a simple ORDER BY would be sufficient in the cypher query.

Input for HLA-A*01:01:01:08:

curl -X 'GET' \
  'http://localhost:8080/features/HLA-A%2A01%3A01%3A01%3A08' \
  -H 'accept: application/json'

Output:
