Description	Flags
command line terminal pods scale to 0	none

Description cvogt 2020-05-22 19:45:20 UTC

Description of problem:
Cloudshell pod never scales to zero. Therefore indefinitely consuming resources per user per terminal.

Prerequisites (if any, like setup, operators/versions):
Install the che-workspace-controller

Steps to Reproduce:
1. Open the OpenShift command line terminal
2. Wait as long as you want to and observe the pod that was created in the namespace where the workspace was created

Actual results:
Pod will be always be present.

Expected results:
After a certain amount of time (TBD) the pod should scale to 0.

Reproducibility (Always/Intermittent/Only Once):
always

Build Details:
4.5.0-0.ci-2020-05-18-204038

Additional info:
Requires https://github.com/openshift/console/pull/5332 to merge.
This PR adds support for the endpoint `/api/terminal/$namespace/$workspaceName/activity/tick`
All we need to do is POST a request to this endpoint every X seconds while the user is active in the terminal.
Suggestion: track how long it's been since the last POST request was sent. If activity occurs later than 1 minute since, then send another POST request.
