Issue #, if available: #1023

Description of changes:

Added a warning message if primary eni has delete on termination set to false.


For UT, I set the delete on termination to false and below ipamd log shows the warning -

    Remove timeout for ipamd startup (aws#874)

    * add configurable timeout for ipamd startup

    Adds a configurable timeout to the aws-k8s-agent (ipamd) startup in the
    entrypoint.sh script. Increases the default timeout from ~30 seconds to
    60 seconds.

    Users can set the IPAMD_TIMEOUT_SECONDS environment variable to change
    the timeout.

    Related: aws#625, aws#865 aws#872

    * This is a local gRPC call, so just try every 1 second indefinitely

    Since we have a liveness probe restarting the probe, we can rely on that to kill the pod.
