Description

feat(chart): videoRecorder getting scripts from external files

Motivation and Context

Update video recorder feature deployed on Kubernetes able to work seamlessly with recently changes:

• SessionId can be fetched when Grid components enable HTTPS.
• Video recorder and uploader can shut down gracefully when Autoscaling is enabled with scalingType: job. Before it was changing pod status to 2/3 NotReady instead of Completed when Node was drained by SE_DRAIN_AFTER_SESSION_COUNT: 1
• Shell scripts implemented for the recorder and uploader are getting from external files which allow users can modify, or replace them more easily.
