[mdelapenya]

What does this PR do?

It separates the configuration of the files and the start of the stack into two Ansible task

Why is it important?

We are seeing the following error:

Even though the error relates to sed, I was able to SSH into the running machine and checked that the kibana config file was indeed modified:

$ cat /home/admin/e2e-testing/cli/config/compose/profiles/fleet/default/kibana.config.yml 
---
server.name: kibana
server.host: "0.0.0.0"

telemetry.enabled: false

elasticsearch.hosts: [ "http://3.145.95.35:9200" ]
elasticsearch.username: elastic
elasticsearch.password: changeme
xpack.monitoring.ui.container.elasticsearch.enabled: true

xpack.fleet.registryUrl: "https://epr-staging.elastic.co"
xpack.fleet.agents.enabled: true
xpack.fleet.agents.elasticsearch.host: "http://3.145.95.35:9200"
xpack.fleet.agents.fleet_server.hosts: ["http://3.145.95.35:8220"]

xpack.encryptedSavedObjects.encryptionKey: "12345678901234567890123456789012"
xpack.fleet.agents.tlsCheckDisabled: true

So I'd like to separate the configuration of the files and the start into two separate Ansible tasks, to better troubleshoot the issue.
