Specify trusted flavors

To designate hosts as trusted:

Configure one or more flavors as trusted by using the nova flavor-key set command. For example, to set the m1.tiny flavor as trusted:
```
$ nova flavor-key m1.tiny set trust:trusted_host trusted
```
Request that your instance be run on a trusted host, by specifying a trusted flavor when booting the instance. For example:
```
$ nova boot --flavor m1.tiny --key_name myKeypairName --image myImageID newInstanceName
```
