Display VM state in GET /vm/:hostname route

[sschneid]

eg. 'pending', 'ready', 'running', or 'destroyed'.

{
  "ok": true,
  "fdte9kozfk780y1": {
    "template": "debian-7-x86_64",
    "lifetime": 1,
    "running": 0.05,
    "state": "running",
    "domain": "delivery.puppetlabs.net"
  }
}

This is in favor of #99.

Are there any durations associated with ready or pending? Similar to how destroyed and running states both set a running key?

clone_time is set in the vmpooler__vm__ Redis hash after the clone task completes:

> hgetall vmpooler__vm__we6f5cndfdn1wov
1) "clone"
2) "2015-05-06 09:46:22 -0700"
3) "template"
4) "centos-5-x86_64"
5) "clone_time"
6) "9.70"
7) "check"
8) "2015-05-06 09:48:54 -0700"

The clone and boot phases are also recorded in daily vmpooler__clone__ and vmpooler__boot__ keys:

> hgetall vmpooler__clone__2015-05-06
1) "redhat-7-x86_64:dp980bus8dbwfda"
2) "8.44"
3) "redhat-7-x86_64:qz8n7qa9d23gd4h"
4) "4.71"
...

> hgetall vmpooler__boot__2015-05-06
1) "ubuntu-1204-x86_64:euxqxgoco9awy3i"
2) "65.60"
3) "sles-11-x86_64:soqpzciiz1wx4pk"
4) "121.58"
...

Hopefully that answers your question?

The spec tests are passing. 👍
