fix: allocation average time queued broken [DET-9709]

[jgongd]

Description

The Avg Queue Time chart in http://{DET_MASTER}/det/resourcepool/default/stats has a queue time of thousands of years. Two reasons: k8s doesn't send allocation start time, and in agent we don't send allocation start time when we restore allocations. The start time is stored as 0001-01-01 00:00:00+00 in the DB.
