Updated DB's automatically from Wazuh-db

• Database auto-upgrade Database auto-upgrade #2059

Description

Since version 3.7 of Wazuh the databases are kept after an update, which implies that after installing a new version where the structure of the agent databases is modified, it forces us to update them.

By a field in the metadata table we know the database version that has an agent. After an update, Wazuh-db, it will check if it is necessary to update it.

Test

• Update from 3.7.0 wazuh-manager and check if database structure becomes updated.
• Check if Wazuh-db creates a backup in case of failing the update.
• Check if the .template.db file is deleted (and recreating only when creating new DB) after an upgrading.
