Add mapping for indexing Patient and Person entities

[rahul6603]

Issue - #1049

Summary

• We will use @Indexed and @*Field (such as @KeywordField) annotations to map Patient and Person entities and their fields to Lucene indexes.
• We will create a custom normalizer that includes lowercase and ascii-folding filters for the Keyword fields. These filters will convert every character to lowercase and replace characters with diacritics ("é", "à", …​) with their ASCII equivalent ("e", "a", …​).
