Rudder

Agent capabilities from inventory (see #9151) are not parsed and store in node info.

Moreover, it is said in #9359 that agent capabilities should be per-agent, not per-node, but the current inventory structure is:

   <RUDDER>
      <AGENT>
        <AGENT_NAME>cfengine-community</AGENT_NAME>
        ....
      </AGENT>
      <AGENT_CAPABILITIES>
        <AGENT_CAPABILITY>cfengine</AGENT_CAPABILITY>
        ....
      </AGENT_CAPABILITIES>

So we also certainly need to update how inventory is done.

I'm setting the target to 4.1 because we need LTS agent to report the correct things, but perhaps that the parsing/save in node can be done in a next major release.
