Add Status to ResourceInfo

[kobergj]

Adds a Status field to the resource info of a resource. This field can be used to signal a meta status of the resource (like "processing", "readytouse", "blocked", ...). For backwards compatibility an empty status should be considered as "ok"

@labkode @vascoguita The Generator seems to be broken, can you investigate why?

@kobergj Can you rebase?

Rediscussed today with @kobergj : this is still valid, though to be "properly usable" it should be an enum with a given list (and extendable) list of values as opposed to an unspecified string.

The current implementation in Reva edge uses an opaque, therefore a code review should be done to identify the actual meaningful values and add them here.
