Changelog of @hackage/eventlog-live 0.8.0.0

0.8.0.0

The version 0.7.0.0 was skipped to avoid confusion with eventlog-live-otelcol-0.7.0.0.

Merge the executable eventlog-live-otelcol into this package as eventlog-live-otlp.
Add support for OpenTelemetry Environment Variable Configuration:

The following SDK configuration options are supported: https://opentelemetry.io/docs/specs/otel/configuration/sdk-environment-variables/#general-sdk-configuration
- OTEL_RESOURCE_ATTRIBUTES
- OTEL_SERVICE_NAME
- OTEL_LOG_LEVEL
- OTEL_TRACES_EXPORTER, OTEL_METRICS_EXPORTER, OTEL_LOGS_EXPORTER, and OTEL_PROFILES_EXPORTER
The following OTLP exporter configuration options are supported: https://opentelemetry.io/docs/specs/otel/protocol/exporter/
- OTEL_EXPORTER_OTLP_ENDPOINT
- OTEL_EXPORTER_OTLP_INSECURE
- OTEL_EXPORTER_OTLP_CERTIFICATE (only by grpc protocol)
- OTEL_EXPORTER_OTLP_CLIENT_KEY (parsed but ignored)
- OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE (parsed but ignored)
- OTEL_EXPORTER_OTLP_HEADERS (only by http/protobuf protocol)
- OTEL_EXPORTER_OTLP_TIMEOUT (parsed but ignored, support to be added in next version)
- OTEL_EXPORTER_OTLP_PROTOCOL (only grpc and http/protobuf protocols are supported)
All special-specific variants of the above environment variables are supported, e.g., OTEL_EXPORTER_OTLP_TRACES_ENDPOINT, OTEL_EXPORTER_OTLP_METRICS_ENDPOINT, OTEL_EXPORTER_OTLP_LOGS_ENDPOINT, and OTEL_EXPORTER_OTLP_PROFILES_ENDPOINT are all parsed and used.

The command-line arguments that controlled these options have been removed:
```
--service-name                   -> OTEL_SERVICE_NAME
--verbosity                      -> OTEL_LOG_LEVEL
--otlp-protocol                  -> OTEL_EXPORTER_OTLP_PROTOCOL
--otlp-endpoint                  -> OTEL_EXPORTER_OTLP_ENDPOINT
--otlp-grpc-certificate-store    -> OTEL_EXPORTER_OTLP_CERTIFICATE
--otlp-http-headers              -> OTEL_EXPORTER_OTLP_HEADERS
```
The --otlp-grpc-ssl-key-log and --otlp-grpc-ssl-key-log-from-env options were removed.

Support for setting a gRPC SSL keylog was removed. If you relied on this, please open an issue.
Support was added for signal-specific exporters, e.g., if you supply different values for OTEL_EXPORTER_OTLP_TRACES_ENDPOINT and OTEL_EXPORTER_OTLP_METRICS_ENDPOINT then traces and metrics are exported to different endpoints.

You can use signal-specific exporter selection to disable certain signals altogether, e.g., OTEL_TRACES_EXPORTER=none causes no traces to be exported.
