Add implementation for XTable REST Service (#704)
* Add module for xtable rest service
* Use builder pattern, spotless fix
* Add unit test for conversion resource
* Refactor code for easier testing, add unit test for service
* Fix other failing modules tests by moving quarkus bom into xtable service
* Add metadata helper utils, test other formats
* Address Vinish intial set of comments
* add unit test for util
* minor fix for other unit test
* spotless
* fix dependency conflict to make unit tests run in ci
* minor mvn fix
* Address Vinish remaining comments
* Address Vinish comments
* Make sourceProviders private final

+# XTable REST Service
+
+The `rest-service-open-api.yaml` defines the api contract for running table
format conversion using XTable's REST service.
+See XTable's `spec` module for more details:
https://github.com/apache/incubator-xtable/tree/main/spec
+
+## How to run the service locally
+
+#### Before running the service, ensure that you have the required credentials
set in your enviroment needed to read and write to cloud storage.
+
+To run the service locally, first ensure you have built the project with
+```sh
+mvn clean install -DskipTests
+```
+
+
+Then you can run start the quarkus service using the following command:
+```sh
+mvn quarkus:dev -pl xtable-service
+```
+This will start the service on `http://localhost:8080`.
+
+Note quarkus will automatically reload the service when you make changes to
the code.
+
+## Testing with Postman
+
+If you would like to test the service with an api client, you can download
Postman https://www.postman.com/downloads/
+
+Ensure that when you are testing that you have set the service URL, headers,
and request body correctly.
+See the screenshots below for an example.
