Update Redpanda to v21.11.2

[vuldin]

This is a minor PR to update Redpanda from v21.5.5 to v21.11.2. There have been 24 releases and many improvements since the latter version (too many features and bug fixes to list in full here). More details on these improvements can be found on the project's release page: https://github.com/vectorizedio/redpanda/releases

One new feature I want to draw attention to is the schema registry subsystem. More details on this feature can be found here: https://redpanda.com/blog/schema_registry/

There have been mentions of creating a schema registry dev service for quarkus so that developers would have easy access to a schema registry in the same way that they currently have access to an event bus during development. With this Redpanda update, there is now another simple and performant option for this future dev service.

I ran tests, and I believe everything went fine for the purposes of this change. But I did run into the following issue when running ./mvnw install -Dnative:

[ERROR] Failed to execute goal io.quarkus:quarkus-maven-plugin:999-SNAPSHOT:build (default) on project quarkus-cli: Failed to build quarkus application: io.quarkus.builder.BuildException: Build failure: Build failed due to errors
[ERROR]         [error]: Build step io.quarkus.deployment.pkg.steps.NativeImageBuildStep#build threw an exception: java.lang.RuntimeException: Cannot find the `native-image` in the GRAALVM_HOME, JAVA_HOME and System PATH. Install it using `gu install native-image`

I assume this error is related to either not having graalvm or not having the right version, but I do have it installed:

> gu --version
GraalVM Updater 21.1.0
> echo $GRAALVM_HOME

@vuldin The error is about not having native-image installed. It's a GraalVM "plugin" (so you need to install it as a second step).
