Track pod resource usage, detect OOM crashes, handle auto-scaling (#1235)
* keep track of per pod status on crawljob:
- crashes time, and reason
- 'used' vs 'allocated' resources 
- 'percent' used / allocated

* crawl log errors: log error when crawler crashes via OOM, either via redis error log
or to console

* add initial autoscaling support!
- detect if metrics server is available via K8SApi.is_pod_metrics_available()
- if available, use metrics for 'used' fields
- if no metrics, set memory used for redis only (using redis apis)
- allow overriding memory and cpu via newMemory and newCpu settings on pod status
- scale memory / cpu based on newMemory and newCpu setting
- templates: update jinja templates to allow restarting crawler and redis with new resources
- ci: enable metrics-server on k3d, microk8s and nightly k3d ci runs

* roles: cleanup unused roles, add permissions for listing metrics

* stats for running crawls:
- update in db via operator
- avoids losing stats if redis pod happens to be done
- tradeoff is more db access in operator, but less extra connections to redis + already
loading from db in backend
- size stat: ensure size of previous files is added to the stats

* crawler deployment tweaks:
- adjust cpu/mem per browser
- add --headless flag to configmap to use new headless mode by default!
