Monitoring

modifications on the iac to make it work for the monitoring agent:

• we split piacere monitoring in two stages, as we were not able to run in a single playbook the galaxy instalation of a role and the usage of that role
• we added the loading of the piacere monitoring vars from the environment so that iem can fill them with the received deployment id and the details of the influxdb and wazuh manager
• for telegraf we added random string for the name if the keypair to avoid conficts
• besides after a security groups quota error we merge the 4 security groups into one, that possibly is more complex and less descriptive unfortunately.
