Bogdan d6ed8246b6 Deprecate all types and funcs in config package
The main reason is to remove the circular dependency between the config (including sub-packages) and component. Here is the current state:
* component depends on config
* config/sub-package[grpc, http, etc.] depends on config & component

Because of this "circular" dependency, we cannot split for example "config" into its own module, only if all the other config sub-packages are also split.

General Information

Extensions provide capabilities on top of the primary functionality of the collector. Generally, extensions are used for implementing components that can be added to the Collector, but which do not require direct access to telemetry data and are not part of the pipelines (like receivers, processors or exporters). Example extensions are: Health Check extension that responds to health check requests or PProf extension that allows fetching Collector's performance profile.

Supported service extensions (sorted alphabetically):

The contributors repository may have more extensions that can be added to custom builds of the Collector.

Ordering Extensions

The order extensions are specified for the service is important as this is the order in which each extension will be started and the reverse order in which they will be shutdown. The ordering is determined in the extensions tag under the service tag in the configuration file, example:

service:
  # Extensions specified below are going to be loaded by the service in the
  # order given below, and shutdown on reverse order.
  extensions: [memory_ballast, zpages]
