oarstat JSON (YAML/XML)

There is no JSON/YAML/XML formated output for oarstat -pj.
output of oarstat -J -fj is the following:

WAITING/job batch

"assigned_resources" : [ ],
"assigned_network_address" : [ ],

→ no information on scheduled resources

WAITING/reservation a l'avance

"reserved_resources" : {

both assigned_resources and reserved_resources show up
no reserved_network_address
reserved_resources is a hash, while assigned_resources and assigned_network_address are tables

OAR 2.5.8

Proposals

oarstat CLI:
- oarstat -pj is only usable for running/ended jobs → no change.
- No change either to oarstat -fj → use JSON/Yaml/XML instead to get the properties
oarstat JSON (Yaml/XML)
- Homogenize the information for assigned resources (running/ended job), scheduled resources (waiting batch job) and reserved resources (advance reservation) AND add the information about the properties → this means changing the user interface of the command, not just add structured information.
Rest API:
- Add the properties in the structure of every resource: this means only adding a properties key in the current hash structure, with the hash of properties as value. → does not change much the user interface.
