[Encoding Extension] Added module outline (#23000)

**Description:**

Adding the required steps to help manage a new component and reduce the
amount of noise generated in one PR.

**Link to tracking Issue:** 

https://github.com/open-telemetry/opentelemetry-collector/issues/6272

**Testing:** 
NA

**Documentation:**

Added the rough outline of the component development to provide more of
a public idea of the project outline.
Not strictly tied to it since it is more a user facing version of the
linked issue.

+<!-- end autogenerated section -->
+
+The encoding extension allows for other components to reference ingress/egress data formats 
+to allow for simplified operability.
+
+_🚧 Under active development 🚧_
+
+## Component Milestones
+
+To help track what work needs to be done with this component, these are the currently active goals being 
+worked towards.
+
+### Development
+
+- CodecFactory: Allows other components to reference code by name and version
+- Codec: Defining the expected interface for a codec
+    - Length Delimited Codec: Used fixed length payloads to represent a collection of data that can be merged together
+- Add existing formats to the codec's libraries.
+- Add support to the following components
+    - `file receiver`
+    - `file exporter`
+    - `kafka receiver`
+    - `kafka exporter`
+    - `kinesis exporter`
+- Add codecs for open source formats, ie: `otlp`, `zipkin`, `jaeger`
+
+Component support will be behind a feature gate to avoid change in behavior
+
+### Alpha
+
+- Adopt vendor formats as codecs 
+- Transition feature gate to default to using encoding extension
+- Add dynamic mapping support for `avro`, `parquet`, and `gotemplate`
+    - Not fixed on these but I am aware that users are interested in these
+
+### Beta
+
+- Add support for remote schema management
+    - Using `AWS Glue`, `kafka schema registry`
+- Performance break down of difference codecs (static, dynamic, remote)
+    - This is more to help provide information to users to expected performance impact.
+
+### Stable
+
+- All features complete
+- Absent of bugs that impact core behaviours
+- Dependencies can also be marked as stable
+
+## Example configuration
+
+```yaml
+extensions:
+  encoding:
+
+receivers:
+  kafka:
+    encoding:
+      name:   zipkin/v1
+      format: proto
+    # ... other configuration values
+```
