[Bug] deployment_sync_secs metrics still emitted for synced subgraphs

Bug report

We're still seeing deployment_sync_secs metrics still emitted for synced subgraphs on v0.31.0.

Specifically, we're still seeing these metrics emitted only when the indexer starts up.

I think this PR was intended to solve this in v0.31.0, but it doesn't seem it fully addresses the issue.

When graph-node starts up, it assumes all subgraphs are not synced; once it processes a block, it determines whether the subgraph is synced and then turns off recording the metric. Depending on how long graph-node was shut down, it can take a bit of time for it to catch up to the chain head. During that time, it will record deployment_sync_secs.

Is that causing an issue for you?

[brianluong]

We noticed deployment_sync_secs for synced subgraphs was a significant contributor to our metrics usage.

To us (and maybe others) deployment_sync_secs are only interesting until the subgraph has synced.
