Support secure WinRM Transport

[mefellows]

Now that WinRM supports a secure transport, we should include this in our Communicator to improve security for public cloud provisioning.

Some thoughts on implementation

• Ideally this is a Communicator wide implementation, not specific to a builder
• Also ideally, we automatically create a local CA, client certs and install into remote machine during boot
• Allow user to specific CA/Certs if they don't want a default PKI implementation
• Allow insecure mode where certs are automatically accepted

I'm currently working on this, have things mostly working. Trying to keep it in pure Go at the moment rather than implicitly depending on OpenSSL, though creating a Windows-compatible certificate seems problematic.

Awesome! Jump on Slack if you want to discuss detail.

Does it need an invite?

[mefellows]

Oh yeah. Hit me up on twitter via DM with your email and I'll send one thru
