Any remote operation where ssh is involved fails on the latest version of x/crypto/ssh

[gigaroby]

Due to this breaking change any operation which uses ssh is destined to fail with this error ssh: must specify HostKeyCallback.

The fix to restore functionality as before is to add HostKeyCallback: ssh.InsecureIgnoreHostKey(), to all instances of ssh.ClientConfig in plumbing/transport/ssh/auth_method.go.
It would also be cool if there was a way to specify the callback directly, perhaps by providing a way to specify ssh.ClientConfig directly?
This affect all projects that aren't vendoring dependencies and download the latest version of x/crypto/ssh.

If you would like me to submit the fix as a PR just say the word.

I think this is already fixed with #346 just not released.

I'm using glide, so i got around it by specifying a ref without the breaking change of crypto/ssh in my glide.yml

- package: golang.org/x/crypto
  ref: 459e26527287adbc2adcc5d0d49abff9a5f315a7
  subpackages:
  - ssh

Yeah, you're right, I forgot to look through closed issues and PR.
Thanks, will close this
