Add ability to set expiration time of headless pods or extend expiration time after launching

[aaronpearlman]

It would be useful to have the ability, both at launch time or after a pod has been launched, to extend the expiration time of a headless pod.

The science portal now provides users with the ability to do this for desktop/notebook sessions. A command-line tool, or an interface to extend headless sessions (e.g., in the Science Portal), would be extremely helpful.

Currently, some of my headless pods require a bit longer than 2 weeks to complete, but the headless sessions expire and are killed before they can finish.

Hi Aaron (and Wes),

I think you can do that now. The command would be an HTTP POST to /session/<sessionid> with payload param action=renew. For example, with curl:

curl -E <mycert.pem> https://ws-uv.canfar.net/skaha/session/<sessionid> -d "action=renew"

I haven't tested this myself, but if you find it doesn't work please let us know. It will add the default expiry time to the session lifetime.
