builder: Add strict version checking when using the builder. Add the temporary flag --skip-strict-versioning for skipping this check. (#9896)
Strict version checking will error on major and minor version mismatches
between the otelcol_version configured and the builder version or versions
in the go.mod. This check can be temporarily disabled by using the --skip-strict-versioning
flag. This flag will be removed in a future minor version.
telemetry: Distributed internal metrics across different levels. (#7890)
The internal metrics levels are updated along with reported metrics:
- The default level is changed from basic to normal, which can be overridden with service::telmetry::metrics::level configuration.
- Batch processor metrics are updated to be reported starting from normal level:
  - processor_batch_batch_send_size
  - processor_batch_metadata_cardinality
  - processor_batch_timeout_trigger_send
  - processor_batch_size_trigger_send
- GRPC/HTTP server and client metrics are updated to be reported starting from detailed level:
  - http.client.* metrics
  - http.server.* metrics
  - rpc.server.* metrics
  - rpc.client.* metrics

manifest with a list of Go modules for your providers.
The modules will work the same as other Collector components.
