Move APIs from Elasticsearch index to the config.yml file.

Hi team,

This PR implements the migration of the APIs from the .wazuh index to the config.yml and the wazuh-registry.json.

Now in the config.yml file, we'll store the APIs entries:

wazuh.hosts: 
  - api1:
      url: http://localhost
      port: 55000
      user: foo
      password: bar
  - api2:
      url: http://localhost
      port: 55000
      user: foo
      password: bar

On the other hand, the wazuh-version.json becomes into wazuh-registry.json and now contents the cluster information associated to the APIs in the config.yml in addition to the Wazuh version and the last restart, etc.

The procedure consists of several steps:

• Migrate from the .wazuh index to the config.yml.
• Clean the documents of the .wazuh index.
• Set the cluster information in the wazuh-registry.json and update in this file instead of the index.
• Read the APIs and cluster information from the config.yml and wazuh-registry.json files.

Also, all the methods which we used to save, edit, remove or check the API have been modified in order to do them work properly.
