Improve the reading of the IP addresses from the config.yml file

[rauldpm]

Description

The config.yml configuration file specifies an IP format of the form ip: <indexer-node-ip>, where <indexer-node-ip> must be replaced by the IP address (including <>), this is not specified in the documentation and we delegate to the users the part where it is understood that the characters < and > must be replaced since they are used as markers.

To avoid this, we should only specify a more understandable option where if there is a delimiter character it is also accepted, for example:

• ip: indexer-node-ip
• ip: "indexer-node-ip"

Another option would be to modify the Wazuh installation assistant so that it removes the delimiter characters in case they are entered.
