Let wcom execute check-manager-config query.

#8356

Description

This PR aims to avoid execd to execute check-manager-config and restart-manager API requests. Now, these requests that were executed by execd will be executed by the wcom thread. This will avoid the problems described in #7968 once this development is completed.

If the check-manager-config request is sent to execd after the change, the following error will appear:

2021/04/26 06:57:29 wazuh-execd: ERROR: (1311): Invalid command name 'check-manager-configuration' provided.

Closes #8356

The exception that is raised is because the API was expecting to connect to the alerts/execa sockets, which is no longer used and it won't be created.
