[FLINK-31866] Start metric window with timestamp of first observation (#573)

The autoscaler uses a ConfigMap to store past metric observations which is used
to re-initialize the autoscaler state in case of failures or upgrades.

Whenever trimming of the ConfigMap occurs, we need to make sure we also update
the timestamp for the start of the metric collection, so any removed
observations can be compensated with by collecting new ones. If we don't do
this, the metric window will effectively shrink due to removing observations.

This can lead to triggering scaling decisions when the operator gets redeployed
due to the removed items.

The solution we are opting here is to treat the first metric observation
timestamp as the start of the metric collection.
