Cancel mechanism for in-flight requests to CRI

[vadasambar]

This ticket is the outcome of conversation in #71 (comment)

TL:DR:

We don't have a mechanism to cancel in-flight requests in case driver pod restarts i.e., we don't have a graceful way to cancel contexts.

TODO

• come up with an approach to cancel in-flight requests on receiving termination signal for the pod
• create a PR
• get it reviewed and merged
• DONE
