Which problem is this PR solving?
We've had problems in the past with the gRPC exporters, as they do not lazy-require the
@grpc/grpc-jslibrary. This causes problems with@opentelemetry/instrumentation-grpcand@opentelemetry/instrumentation-http. This PR addresses this by re-structuring internals in a way that@grpc/grpc-jsis only required on the first export.Fixes #4151
Fixes #4266 (now loads gRPC on export, instead of the next tick, which means this should not happen anymore IF the SDK/exporter is shut down properly before the test environment is torn down).

Breaking changes
Removes
getServiceClientType()This affects
@opentelemetry/exporter-trace-otlp-grpc@opentelemetry/exporter-logs-otlp-grpc@opentelemetry/otlp-grpc-exporter-base(intended for internal use only)It was previously possible to get the service client type (Traces, Metrics, Logs) from the exporter - this is now not possible anymore. This was used internally to construct a service client. Due to the restructuring of the internals in this PR, this is now not needed anymore.
Possible impact: low this returned a static string that did not change per-exporter.
Removes
getServiceProtoPath()This affects
@opentelemetry/exporter-trace-otlp-grpc@opentelemetry/exporter-logs-otlp-grpc@opentelemetry/otlp-grpc-exporter-base(intended for internal use only)It was previously possible to get the service proto path used by exporter - this is now not possible anymore. This was used internally to construct a service client. Due to the restructuring of the internals in this PR, this is now not needed anymore.
Possible impact: low this returned a static string that did not change per-exporter.
Removes
metadataproperty, this affects@opentelemetry/exporter-trace-otlp-grpc@opentelemetry/exporter-logs-otlp-grpc@opentelemetry/otlp-grpc-exporter-base(intended for internal use only)It was previously possible to edit metadata while the exporter is running. This is likely not an intended feature as the property was only read in the internal export code and tests, but only written by the exporters themselves.
Possible impact: medium users could have used the
metadataproperty to dynamically modify metadata while the export is running.Removes
serviceClientproperty, this affects@opentelemetry/exporter-trace-otlp-grpc@opentelemetry/exporter-logs-otlp-grpc@opentelemetry/otlp-grpc-exporter-base(intended for internal use only)This was likely also intended for internal use but unintentionally exposed to users. It allowed full access to the internally used grpc service client.
Possible impact: unknown users could have used the service client directly to modify export behavior.
Removes
compressionproperty, this affects@opentelemetry/exporter-trace-otlp-grpc@opentelemetry/exporter-logs-otlp-grpc@opentelemetry/otlp-grpc-exporter-base(intended for internal use only)This was likely also intended for internal use but unintentionally exposed to users. It allowed reading the compression property. It was read when a new service client was created, but changes to it would not affect the export.
Possible impact: low, if needed it can be read from the config that's passed to the constructor
