Added struct to be passed to the Process function to render the vagrant ...

Instead of 1024m it shoud be 1024M. Using 1024m as value does not work:

Fix broken links docker builder docs.

The first link is to an outside page that doesn't exist anymore.
The second link is to the correct id.

the ovftool can't refer to an object vi address without a "/" at the end of the address

Portability and explicitness

"Explicivity" is not a word.

This changes the SaltStack bootstrap URL to use the HTTPS link from the commercial site.  Alternatives are the HTTPS link to the raw file on GitHub, but this, whilst more transparent, might break down the line.

Otherwise, the error message will be displayed in GUI:
"Unable to connect CD/DVD 0"

Switch to hashicorp/go-msgpack

Clean VMX step should always remove floppy.
