builder/virtualbox-ovf,vmware-vmx: add boot_command support

[rasa]

Fixes #1082

[rickard-von-essen]

@rasa can you also add the Boot Command section from virtualbox-iso.html.markdown to the virtualbox-ovf.html.markdown.

[hoshposh]

Will this be merged soon? It appears to have the doc that @rickard-von-essen asked for.

[rasa]

It's scheduled to be included in the next release.

[routelastresort]

@rasa - every time I try boot commands (upon the first one entered, e.g. a carriage return), it will try to execute a VBoxManage poweroff and unregister, and crash (because it can't unregister a locked VM). It never tries to execute any boot commands. Do you have a working environment and/or example template?

EDIT: this happens to me w/vmware-vmx as well

[routelastresort]

It looks like step_http_server needs to also be moved to common (after spending a ton of time with this) :)

... and in vmware-vmx, the builder is lacking the VNC portion (which is used for boot commands)

[mitchellh]

Looks great. I'm pulling this in. @routelastresort I'll take a look at those, thanks.

[mitchellh]

@routelastresort I added HTTP server support to OVF. I'm fixing VMware now.

[routelastresort]

Many thanks - your patches looked similar enough to my fork, but I'll go back and check!

[mitchellh]

There seemed to be only one way to cook that turkey, so I'm sure they're pretty close.
