[feature] Support OTLP HTTP, drop Jaeger (#2184)

* [feature] Add http trace exporter, drop Jaeger

Jaeger supports ingesting traces using the OpenTelemetry gRPC or HTTP
methods. The Jaeger project has deprecated the old jaeger transport.

* Add support for submitting traces over HTTP
* Drop support for the old Jaeger protocol
* Upgrade the trace libraries to v1.17

### Added
- Export the `ManualReader` struct in `go.opentelemetry.io/otel/sdk/metric`. (#4244)
- Export the `PeriodicReader` struct in `go.opentelemetry.io/otel/sdk/metric`. (#4244)
- Add support for exponential histogram aggregations.
A histogram can be configured as an exponential histogram using a view with `"go.opentelemetry.io/otel/sdk/metric".ExponentialHistogram` as the aggregation. (#4245)
- Export the `Exporter` struct in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`. (#4272)
- Export the `Exporter` struct in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`. (#4272)
- The exporters in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric` now support the `OTEL_EXPORTER_OTLP_METRICS_TEMPORALITY_PREFERENCE` environment variable. (#4287)
- Add `WithoutCounterSuffixes` option in `go.opentelemetry.io/otel/exporters/prometheus` to disable addition of `_total` suffixes. (#4306)
- Add info and debug logging to the metric SDK in `go.opentelemetry.io/otel/sdk/metric`. (#4315)
- The `go.opentelemetry.io/otel/semconv/v1.21.0` package.
The package contains semantic conventions from the `v1.21.0` version of the OpenTelemetry Semantic Conventions. (#4362)
- Accept 201 to 299 HTTP status as success in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` and `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`. (#4365)
- Document the `Temporality` and `Aggregation` methods of the `"go.opentelemetry.io/otel/sdk/metric".Exporter"` need to be concurrent safe. (#4381)
- Expand the set of units supported by the Prometheus exporter, and don't add unit suffixes if they are already present in `go.opentelemetry.op/otel/exporters/prometheus` (#4374)
- Move the `Aggregation` interface and its implementations from `go.opentelemetry.io/otel/sdk/metric/aggregation` to `go.opentelemetry.io/otel/sdk/metric`. (#4435)
- The exporters in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric` now support the `OTEL_EXPORTER_OTLP_METRICS_DEFAULT_HISTOGRAM_AGGREGATION` environment variable. (#4437)
- Add the `NewAllowKeysFilter` and `NewDenyKeysFilter` functions to `go.opentelemetry.io/otel/attribute` to allow convenient creation of allow-keys and deny-keys filters. (#4444)
- Support Go 1.21. (#4463)
### Changed
- Starting from `v1.21.0` of semantic conventions, `go.opentelemetry.io/otel/semconv/{version}/httpconv` and `go.opentelemetry.io/otel/semconv/{version}/netconv` packages will no longer be published. (#4145)
- Log duplicate instrument conflict at a warning level instead of info in `go.opentelemetry.io/otel/sdk/metric`. (#4202)
- Return an error on the creation of new instruments in `go.opentelemetry.io/otel/sdk/metric` if their name doesn't pass regexp validation. (#4210)
- `NewManualReader` in `go.opentelemetry.io/otel/sdk/metric` returns `*ManualReader` instead of `Reader`. (#4244)
- `NewPeriodicReader` in `go.opentelemetry.io/otel/sdk/metric` returns `*PeriodicReader` instead of `Reader`. (#4244)
- Count the Collect time in the `PeriodicReader` timeout in `go.opentelemetry.io/otel/sdk/metric`. (#4221)
- The function `New` in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` returns `*Exporter` instead of `"go.opentelemetry.io/otel/sdk/metric".Exporter`. (#4272)
- The function `New` in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` returns `*Exporter` instead of `"go.opentelemetry.io/otel/sdk/metric".Exporter`. (#4272)
- If an attribute set is omitted from an async callback, the previous value will no longer be exported in `go.opentelemetry.io/otel/sdk/metric`. (#4290)
- If an attribute set is observed multiple times in an async callback in `go.opentelemetry.io/otel/sdk/metric`, the values will be summed instead of the last observation winning. (#4289)
- Allow the explicit bucket histogram aggregation to be used for the up-down counter, observable counter, observable up-down counter, and observable gauge in the `go.opentelemetry.io/otel/sdk/metric` package. (#4332)
- Restrict `Meter`s in `go.opentelemetry.io/otel/sdk/metric` to only register and collect instruments it created. (#4333)
- `PeriodicReader.Shutdown` and `PeriodicReader.ForceFlush` in `go.opentelemetry.io/otel/sdk/metric` now apply the periodic reader's timeout to the operation if the user provided context does not contain a deadline. (#4356, #4377)
- Upgrade all use of `go.opentelemetry.io/otel/semconv` to use `v1.21.0`. (#4408)
- Increase instrument name maximum length from 63 to 255 characters in `go.opentelemetry.io/otel/sdk/metric`. (#4434)
- Add `go.opentelemetry.op/otel/sdk/metric.WithProducer` as an `Option` for `"go.opentelemetry.io/otel/sdk/metric".NewManualReader` and `"go.opentelemetry.io/otel/sdk/metric".NewPeriodicReader`. (#4346)
### Removed
- Remove `Reader.RegisterProducer` in `go.opentelemetry.io/otel/metric`.
Use the added `WithProducer` option instead. (#4346)

- The `ManualReader` will not panic if `AggregationSelector` returns `nil` in `go.opentelemetry.io/otel/sdk/metric`. (#4350)
