public HealthCheckedEndpointGroupBuilder useGet(boolean useGet) {
        this.useGet = useGet;
        return this;
    }
Sets whether to use HTTP {@code GET} method instead of {@code HEAD} when sending a health check request.
By default, {@code HEAD} method is used. This can be useful when the health check requests are failing
due to a bad request or an authorization failure and you want to learn why.
