[Bug] graph-node:v0.34.0 metrics bloat

[trader-payne]

Bug report

The /metrics endpoint of the graph-node is bloated massively after the 0.34.0 upgrade, coming mainly from deployment_eth_call_execution_time metrics.

Tests have been done syncing one subgraph from scratch, and polling /metrics after some time.
