[rest] Fix GetTableResponse should return fields

[JingsongLi]

Purpose

Modify GetTableResponse:

public class GetTableResponse implements RESTResponse {

    private static final String FIELD_PATH = "path";
    private static final String FIELD_SCHEMA_ID = "schema-id";
    private static final String FIELD_SCHEMA = "schema";

    @JsonProperty(FIELD_PATH)
    private final String path;

    @JsonProperty(FIELD_SCHEMA_ID)
    private final long schemaId;

    @JsonProperty(FIELD_SCHEMA)
    private final Schema schema;
}

We should use Schema instead of TableSchema to keep one serialization implementation.

UpdateTable to RenameTable

UpdateTable should be refactored, because we need a unified SchemaChange to support changes.
