Add one method for LinkisDataSourceRemoteClient

  def createClientConfig(): DWSClientConfig = {
    val serverUrl = Configuration.getGateWayURL()
    if(StringUtils.isEmpty(serverUrl)) throw new DataSourceClientBuilderException("serverUrl cannot be null.")

    val maxConnection: Int = CONNECTION_MAX_SIZE.getValue
    val connectTimeout: Int = CONNECTION_TIMEOUT.getValue
    val readTimeout: Int = CONNECTION_READ_TIMEOUT.getValue
    val tokenKey = AUTH_TOKEN_KEY.getValue
    val tokenValue = AUTH_TOKEN_VALUE.getValue

    val authenticationStrategy: AuthenticationStrategy = new TokenAuthenticationStrategy()
    DWSClientConfigBuilder.newBuilder()
      .addServerUrl(serverUrl)
      .connectionTimeout(connectTimeout)
      .discoveryEnabled(false)
      .discoveryFrequency(1, TimeUnit.MINUTES)
      .loadbalancerEnabled(true)
      .maxConnectionSize(maxConnection)
      .retryEnabled(false)
      .readTimeout(readTimeout)
      .setAuthenticationStrategy(authenticationStrategy)
      .setAuthTokenKey(tokenKey)
      .setAuthTokenValue(tokenValue)
      .setDWSVersion(Configuration.LINKIS_WEB_VERSION.getValue)
      .build()
  }
