Add kafka/{zookeeper,producer,consumer}

[mackjmr]

App changes:

• Adds a Java based producer service (orderproducer) which produces to the orders topic.
• Adds a zookeeper service which the kafka service connects to
• Makes frauddetectionservice and kafka expose JMX

Agent changes:

• Adds integration for kafka on producer, consumer, broker
• Adds zookeeper integrations
• Enables logs

Kafka OOTB Dashboard:

• env:otel-ingest => LINK. Filtered on otel-ingest, we can see all dashboard components are populated.
• env:otel => LINK. Filtered on otel, only 3 metrics are present.

Unrelated change:
It also add rules:

    - if: '$CI_COMMIT_REF_NAME == "prod"'
    - if: '$CI_COMMIT_REF_NAME =~ /-staging$/'

so that deploy is only done for prod and *-staging branches.
