Wazuh Agent different path installation

[brmb]

Issue:
There is no possibility to install wazuh-agent via RPM/DEB to another directory (default is /var/ossec).
I want to install it on /opt/ossec because /var/ossec is already occupied by another tool.

Solution:
I would like developers to treat this as a feature request to get this improved/fixed,so that wazuh_dir or another variable, would influence Wazuh Agent installation path.

P.S. I'm aware about ability to install Wazuh Agent to different path if I recompile RPM/DEB packages, however that is not ideal approach in many ways, i.e., it does not allow to do a smooth wazuh-agent upgrade.
