Bootstrap via chef_core

Make bootstrap use train via chef_core/TargetHost

This commit implements usage of TargetHost instead of
knife_ssh.  TargetHost is a platform-independent representation
of a Train connection. It abstracts common operations
(such as file upload/download, permissions, temp directories,
command executation, etc) and connection error handling.

Moving to TargetHost and train gives us the ability to
execute commands on the bootstrap target; instead of
running sh -c 'long-command-string-containing-secrets', we'll
now upload the bootstrap script to a temporary directory on the
bootstrap target and execute it there.

Incorporating WinRM support directly (allowing core support
for Windows bootstraps, without the knife-windows plugin)
will follow.

THis also improves unit test coverage of the bootstrap module,
and clarifies functional versus behavior tests in that space
