As the winds of a Notebook 6.0 release are blowing, we need to get some of the recent fixes in NB2KG into the Gateway module for Notebook since 6.0 marks the first release in which the extension is embedded in Notebook.

The ported changes are the following:

  1. Increase http timeout default values nb2kg#35, Ensure request-timeout is > launch-timeout + pad nb2kg#38: Modify/add various timeout values and ensure the request timeout is greater than the kernel launch timeout.
  2. Allow KG_HEADERS to specify Authorization without being overwritten  nb2kg#30: Add authorization token to header only if no authorization already present. @chuyqa - could you please confirm these changes are correct.
  3. Add keepalive websocket ping nb2kg#29: Add keepalive ping on gateway websocket. @esevan - could you please confirm these changes are correct.

Once Notebook 6.0 is available, we will move NB2KG into maintenance mode.

cc: @Zsailer - we'll want this PR included in the list at jupyter-server/jupyter_server#53. Thanks!

Setting milestone 6 at @lresende's request

The connect and request timeout defaults have been updated from 20 to 60
seconds and a default value of 40 has been added for KERNEL_LAUNCH_TIMEOUT.
The code ensures that KERNEL_LAUNCH_TIMEOUT is in the env and that the
value of the request timeout is at least 2 greather than KERNEL_LAUNCH_TIMEOUT.

This PR is port of the NB2KG PRs 35 and 38.
