Bump otel dependencies to v0.115.0/v1.21.0

[dricross]

Description of the issue

We need to track and pull in changes from upstream periodically.

Major changes to lookout for:

• receiver.CreateSettings renamed to receiver.Settings: Bump otel dependencies to v0.115.0/v1.21.0 #1485 (comment). Many changes like this
• pipelines.Config now requires a pipelines.ID rather than component.ID
  • Change the Translator / TranslatorMap generic functions to also accept another type, ID
  • For component translators, this ID is component.ID. For pipeline translators, this ID is pipeline.ID.
  • Component translators are then the concrete type Translator[component.Config, component.ID], which mean “given a config, generate a component.Config which is identified by a component.ID”
  • Pipeline translators are the concrete type Translator[*ComponentTranslators, pipeline.ID], which means “given a config, generate a ComponentTranslator (a loose definition of an otel pipeline) which is identified by a pipeline.ID”
• Upstream update to TracesConfig adds new field: open-telemetry/opentelemetry-collector@b33913b
  • Generated otel.Config now has a new field under Service.Telemetry.Level which is set to Basic by default
  • Add level: Basic to basically all the expected yaml files
• Otel config decoder no longer supports "weakly typed" values by default
  • no longer accepts “true” for local_mode setting. Must be true
  • no longer accepts [] for external_labels setting. Must be {}
  • This is due to a upstream change: open-telemetry/opentelemetry-collector@e477c3a
  • Previously, the “weak typing” was enforced so the decoder would know to convert a string to a boolean. With “strong typing” enforced by default, the decoder will no longer accept it
• New defaults for clientConfig
  • open-telemetry/opentelemetry-collector@4d0b088
  • fields don’t appear to be used by component directly. Used by Go’s http.Transport
  • The values are pulled from go’s http.DefaultTransport
    • ReadBufferSize: previously 0, which leaves transport.ReadBufferSize as the default, which is the same thing it’s doing now
    • WriteBufferSize: previously 0, which leaves transport.WriteBufferSize as the default, which is the same thing it’s doing now
    • Headers: previously nil, now empty map. No difference: https://github.com/open-telemetry/opentelemetry-collector/blob/config/confighttp/v0.116.0/config/confighttp/confighttp.go#L216
    • MaxIdleConnsPerHost: previously nil, whichleaves transport.MaxIdleConnsPerHost as the default, which is the same thing it’s doing now
    • MaxConnsPerHost: previously nil, which leaves transport.WriteBufferSize as the default, which is the same thing it’s doing now
    • IdleConnTimeout: previously nil, which leaves transport.WriteBufferSize as the default, which is the same thing it’s doing now
• New defaults for server config (similar to clientConfig)
  • open-telemetry/opentelemetry-collector@0e14c22
  • These new fields set the http.Server settings: https://github.com/open-telemetry/opentelemetry-collector/blob/0e14c22e45fcef9561768753ccf829f03681d11b/config/confighttp/confighttp.go#L488-L491. The change essentially manually sets the http.Server settings to the defaults. No functional change but it shows up in the config file now
• debugexporterhas new field: open-telemetry/opentelemetry-collector@f47b9f2
  • Setting to true maintains previous functionality
• receiver/awscontainerinsightsreceiver/internal/host:
  • newNodeCapacity argument changed to any function but windows tests were not updated: amazon-contributing/opentelemetry-collector-contrib@d5d6147
