Josh Wood b56c0f5609 Docs/vmware-backdoor: Rename backdoor to guestinfo
Based on results of google searches on a few possible titles
to improve on the connotation of backdoor, Guestinfo Configuration
Interface (as part of the RPC API) seems recognizable in vmware
circles. Friends call it just guestinfo.

This changeset also makes docs and usage for this flag appear with
a single hypen (-flag) like most go programs do.

# VMWare Guestinfo Interface
## Cloud-Config VMWare Guestinfo Variables
coreos-cloudinit accepts configuration from the VMware RPC API's *guestinfo*
facility. This datasource can be enabled with the `-from-vmware-guestinfo`
flag to coreos-cloudinit.
The following guestinfo variables are recognized and processed by cloudinit
when passed from the hypervisor to the virtual machine at boot time. Note that
property names are prefixed with `guestinfo.` in the VMX, e.g., `guestinfo.hostname`.
| guestinfo variable | type |
|:--------------------------------------|:--------------------------------|
| `hostname` | `hostname` |
| `interface.<n>.name` | `string` |
| `interface.<n>.mac` | `MAC address` |
| `interface.<n>.dhcp` | `{"yes", "no"}` |
| `interface.<n>.role` | `{"public", "private"}` |
| `interface.<n>.ip.<m>.address` | `CIDR IP address` |
| `interface.<n>.route.<l>.gateway` | `IP address` |
| `interface.<n>.route.<l>.destination` | `CIDR IP address` |
| `dns.server.<x>` | `IP address` |
| `coreos.config.data` | `string` |
| `coreos.config.data.encoding` | `{"", "base64", "gzip+base64"}` |
| `coreos.config.url` | `URL` |
Note: "n", "m", "l", and "x" are 0-indexed, incrementing integers. The
identifier for an `interface` does not correspond to anything outside of this
configuration; it serves only to distinguish between multiple `interface`s.
The guide to [booting on VMWare][bootvmware] is the starting point for more
information about configuring and running CoreOS on VMWare.
