Support pushing of Helm charts to OCI registries

[guiliguili]

Description

With the release of Helm 3.8.0, Helm is able to store and work with charts in container registries, as an alternative to Helm repositories (c.f. Storing Helm Charts in OCI Registries).

This is a feature request to add support for oci in the helm-push goal.

Info

• Eclipse JKube version : 1.7.0
• Maven version (mvn -v) :

Maven home: /usr/local/Cellar/maven/3.8.3/libexec
Java version: 17, vendor: Homebrew, runtime: /usr/local/Cellar/openjdk/17/libexec/openjdk.jdk/Contents/Home
Default locale: en_FR, platform encoding: US-ASCII
OS name: "mac os x", version: "12.2.1", arch: "x86_64", family: "mac"

This would provide a vendor independant alternative to the existing HTTP based repositories currently supported.

FYI I tried the following configuration :

<plugin>
  <groupId>org.eclipse.jkube</groupId>
  <artifactId>kubernetes-maven-plugin</artifactId>
  <configuration>
      <helm>
          <stableRepository>
              <name>local-stable-repo-id</name>
              <url>oci://localhost:5100/helm-charts</url>
              <type>ARTIFACTORY</type>
          </stableRepository>
          <snapshotRepository>
              <name>local-snapshot-repo-id</name>
              <url>oci://localhost:5100/helm-charts</url>
              <type>ARTIFACTORY</type>
          </snapshotRepository>
      </helm>
  </configuration>
  </plugin>
</plugin>

And I not surprisingly got the following error :
