This PR allows a single API request to return multiple VM objects. It
supports the following formats:
- POST <json> /vm/
eg. 'curl -d '{"debian-7-i386":"3","debian-7-x86_64":"1"}' --url vmpooler/vm
- POST /vm/<pool>+<pool>+<pool>...
eg. 'curl -d --url vmpooler/vm/debian-7-i386+debian-7-i386+debian-7-i386+debian-7-x86_64
Both commands listed above will return a JSON hash of 3 debian-7-i386 VMs and
1 debian-7-x86_64 VM:
{
"ok": true,
"debian-7-i386": {
"hostname": [
"v49pwwk5yzg6oad",
"ylghlgote5uso54",
"wt0c4xovvulo7ge"
]
},
"debian-7-x86_64": {
"hostname": "v3dkrulttp360fm"
}
}
