Add commands by asset DTOs

[boricj]

Needed for requesting list of assets supporting a particular power action.

I think this should be inside asset source code and not here. @stark-dev could you take a look ?

Not sure if this is intended to query directly fty-nut or existing assets. Currently I don't think we have a way to get the commands supported by an asset in fty-asset, is it something we should add?

Everything related to NUT commands is handled by the agent fty-nut-command. Similarly, IT actions on IT assets are handled by EMC4J2. fty-asset really has no concept of actions and no component in the system has a global overview of asset actions.

Folding all of this inside a centralized action provider mechanism is going to require lots of design and work, as actions provided by dedicated components (fty-nut-command, EMC4J2...) will need to be both registered for enumeration and delegated for execution, not counting the fact that this would be a cross-team endeavor. I'm not going to to that for now, so I'm just going to extend this particular provider of actions to address that particular use case instead.

Thanks, with @perrettecl we were discussing the possibility of adding an advanced filter for listing assets based on some of their properties, but it is not necessarily related, just wondering if it could be merged in some way
