GraphQL node query

[steven-sheehy]

Problem

As a consumer of the mirror node GraphQL API, I'd like to be able to query for a generic Node by it's opaque ID for purposes of caching or refreshing the data.

Solution

• Implement the node(id: ID! @Pattern(regexp: "^[a-zA-Z0-9+/=]+$")): Node query
• Parse the ID into the underlying domain type
• Delegate query to appropriate service or controller to do the query, passing it the primary key(s) encoded in the ID.
