Vulnerability Detection E2E tests: Outdated configuration

[Rebits]

Description

The latest update in version 4.8.0 - Beta 4 introduces significant modifications to the vulnerability detection module's configuration and behavior. As a result, these alterations have caused the E2E Vulnerability Detection test to fail consistently.

Investigation is imperative to identify and implement the necessary adjustments to the tests

Currently, using the test's configuration produced the following errors in the environment:

2024/03/20 10:41:30 wazuh-modulesd: WARNING: (1230): Invalid element in the configuration: 'indexer.certificate'.
2024/03/20 10:41:30 wazuh-modulesd: WARNING: (1230): Invalid element in the configuration: 'indexer.key'.

	<indexer>
		<enabled>yes</enabled>
		<hosts>
			<host>https://INDEXER-IP:9200</host>
		</hosts>
			<ssl>
			<certificate_authorities>
				<ca>/etc/pki/filebeat/root-ca.pem</ca>
			</certificate_authorities>
		</ssl>
		<certificate>/etc/pki/filebeat/node-2.pem</certificate>
		<key>/etc/pki/filebeat/node-2-key.pem</key>
	</indexer>

Changed test configuration to:

	<indexer>
		<enabled>yes</enabled>     
		<hosts>
			<host>https://INDEXER-API:9200</host>  
		</hosts>
		<ssl>
			<certificate_authorities>
				<ca>/etc/pki/filebeat/root-ca.pem</ca>
			</certificate_authorities>
			<certificate>/etc/pki/filebeat/node-2.pem</certificate>
			<key>/etc/pki/filebeat/node-2-key.pem</key>
		</ssl>
	</indexer>

Now, indexer connector is working as expected

2024/03/20 11:05:55 indexer-connector: INFO: IndexerConnector initialized.

2024/03/20 11:05:56 wazuh-modulesd:vulnerability-scanner: INFO: Vulnerability scanner module started

---

Updates the regex for waiting until the end of the vulnerability content process to:

INFO: Vulnerability scanner module started
