Update modules to 0.85.0 and add storage/filestorage extension

[jaehnri]

The storage/filestorage extension is necessary to persist a filelog's tail offset as mentioned in rancher/opni#1708.

plugin/logging:

Notice this version has been tested with Opni. Whenever this version is used, the following line must be removed:
https://github.com/rancher/opni/blob/f12c766d6bbcbed43218223c742d58ccf3dbae99/pkg/resources/preprocessor/workloads.go#L73

plugin/metrics:

Apparently, metrics are running fine:

However, there might be something wrong with Prometheus endpoint scraping, as per the aggregator logs:

2023-09-20T18:46:15.569Z	warn	internal/transaction.go:123	Failed to scrape Prometheus endpoint	{"kind": "receiver", "name": "prometheus/discovered", "data_type": "metrics", "scrape_timestamp": 1695235575564, "target_labels": "{__name__=\"up\", instance=\"10.42.0.44:8443\", job=\"apiserver\"}"}

In this PR, if we don't want to update to 0.85.0 due to the possible breaking changes, we can also opt to only add the filestorage extension. However:

• we will need to deal with Dependency error trying to build custom collector distribution 0.81.0 within a workspace open-telemetry/opentelemetry-collector#8127. It's an easy fix, but might bring breaking changes too.
• we will have to update to 0.85.0 soon anyway due to the opensearch trace exporter.

Has metrics collection been tested with v0.85? In particular need to make sure the opni admin grafana dashboards work with the OTEL driver

@alexandreLamarre ah, no. Might need some help with that...
