[upstream commit 20bba35]

The eventcache API provides 2 handlers.

These are:
RetryInternal -> called to setup process information Retry -> called to setup pod information

In the case of clone events, we used to have en empty implementation on the Retry handler. This results in an issue with missing pod information which is described in detail here: #2902

This patch provides the proper Retry implementation to handle also those cases.

FIXES: #2902
