Change cluster files to make it enabled by default

[Selutario]

Related issue
Closes #13351

Description

Removed cluster options:

• Disabled
• Key
• Name

Changed default value:

• nodes is now 127.0.0.1 instead of NODE_IP.
• node_name is now the hostname instead of node01 (changes in core will be required as explained here).

Added cluster options:

• certfile: Path to certfile (default value is /var/ossec/etc/sslmanager.cert).
• keyfile: Path to keyfile (default value is /var/ossec/etc/sslmanager.key).
• keyfile_password: Keyfile password if any (default value is '')

In addition, when 127.0.0.1 is used as bind_addr in a master node, it means that workers won't be able to connect. As a consequence, children processes creation is disabled in the wazuh-clusterd process of the master node. Most of the tasks (Local integrity, Local agent-groups, Sendsync, etc) are disabled too.

Some warnings and info messages are shown in the cluster.log to notify all this:

# /var/ossec/bin/wazuh-clusterd -f
