(Task 4) Feature: get Race by ID

[Cuttsy27]

Changes

• added GetRace rpc and GetRaceRequest message
• added base SQL query for get race
• added Get method to races repo interface and implemented
• added tests for new get race service

Summary

Adding the new GetRace RPC means users can retrieve just the race they want by providing the Race ID. This will improve performance where only a single Race is required by reducing time spent filtering and reducing bytes sent between client and server. The GetRace RPC and GetRaceRequest message follow Google's AIP-131 Standard Methods: Get by using the HTTP GET verb for the request, using /races/{id} hierarchical format, and expecting a single parameter (id) to retrieve the resource. It also follows syntax-specific requirements such as the RPC name beginning with "Get", the RPC returning the resource type "Race" directly (not "RaceResponse" or similar), and naming the message "RaceRequest".

Example

curl -X "GET" "http://localhost:8000/v1/races/1" \
     -H 'Content-Type: application/json'

Tests

• added racing service tests for the new GetRace functionality
