At present, when using the packer fix command on a template that has
"ssh_private_ip" set to anything but a boolean value, the fixer will
fail, and appear to fail silently, simply returning a non-zero status
code without any message.
To determine what happened, users have to know to set PACKER_LOG=1 to
make the log message visible.
So far as I can tell, this is the only instance of log.Fatalf being
called, and based on the surrounding code the better solution would be
to return an error, which will then be visible to users of packer fix
without having to look in the logs.
The "ssh_private_ip" key works with either boolean values or string
representations of booleans. The fixer errors when the value is defined
as, for example, "true" (with quotation marks). This commit will attempt
to convert the string into a bool when necessary to ensure this case is
handled.
