   * When looking at this specific example, we can see that:

   * **NB:** If the `path_template` field is not provided, the key name is
   * equal to the field name, and the whole field should be sent as a value.
   * This makes the pattern for the field and the value functionally equivalent
   * to `**`, and the configuration
   *     {
   *       field: "table_name"

     *     path_template: "projects/&#42;&#47;{table_location=instances/&#42;}/tables/&#42;"
     *                                                ^            ^
     *                                                |            |
     *       In the {} brackets is the pattern that --             |
     *       specifies what to extract from the                    |
     *       field as a value to be sent.                          |
     *                                                             |
     *      The string in the field must match the whole pattern --
     *      before brackets, inside brackets, after brackets.
     * When looking at this specific example, we can see that:
     * - A key-value pair with the key `table_location`
     *   and the value matching `instances/&#42;` should be added
     *   to the x-goog-request-params routing header.
     * - The value is extracted from the request message's `table_name` field
     *   if it matches the full pattern specified:
     *   `projects/&#42;&#47;instances/&#42;&#47;tables/&#42;`.
     * **NB:** If the `path_template` field is not provided, the key name is
     * equal to the field name, and the whole field should be sent as a value.
     * This makes the pattern for the field and the value functionally equivalent
     * to `**`, and the configuration
     *     {
     *       field: "table_name"
     *     }
     * is a functionally equivalent shorthand to:
     *     {
     *       field: "table_name"
     *       path_template: "{table_name=**}"
     *     }
     * See Example 1 for more details.
