Add support for hypervisor-stats and hypervisor-uptime command

[Lin Hua Cheng]

Add support for the command hypervisor-stats in OSC by enhancing: "osc hypervisor list" to take additional argument:
* --stats show the hypervisor-stats information

And to support hypervisor-uptime, enhance "osc hypervisor show" to take an additional argument:
* --uptime show the hypervisor-uptime information

[Steve Martinelli (stevemar)]

what do the stats look like? should it be --long instead?

[Lin Hua Cheng (lin-hua-cheng)]

Running the hypervisor-stats in nova CLI returns:

+----------------------+-------+
| Property | Value |
+----------------------+-------+
| count | 1 |
| current_workload | 0 |
| disk_available_least | 13 |
| free_disk_gb | 29 |
| free_ram_mb | 3377 |
| local_gb | 29 |
| local_gb_used | 0 |
| memory_mb | 3953 |
| memory_mb_used | 576 |
| running_vms | 1 |
| vcpus | 2 |
| vcpus_used | 1 |
+----------------------+-------+

Seem like is an aggregated data. From the nova client docs, it is described "Get hypervisor statistics over all compute nodes."
