deploy(apollo-rhworker): add preCommand and postCommand values for cronjobs (#3)

* deploy(apollo-rhworker): add preCommand and postCommand values for cronjobs

We don't want to assume a user will be running this with Istio as the
RESF is, so we don't always need to kill the istio proxy in this manner

This change moves the existing trap/curl command to terminate the istio
proxy into values.yaml for our deployment allowing it to be overwritten
for others needs

* feat: automatically terminate cronjob after 5 minutes
