Add support for powershell credential to VMware train

[rlakey]

Describe the Enhancement:

Using a powershell credential to connect to vCenter/ESXi with the VMware train. PowerCLI already supports this natively with the -Credential option on Connect-VIServer.

Describe the Need:

This will allow more credential options like using a smartcard/token for authentication and would be more secure than using environmental variables or username/password.

Current Alternative

None that i know of

Can We Help You Implement This?:

Yes

It looks like to implement this we could make the following modifications to the vmware transport.

https://github.com/inspec/train/blob/master/lib/train/transports/vmware.rb

Add a credential option after line 13. This might have to be restricted to an environment variable right now since it is a PowerShell construct and ruby won't know what it is. It might also not work if ruby is unable to handle the credential object.

Add a clause for if a credential is defined at line 53 to change the command used to connect.

Another thought would be to have an option where the vCenter connection was handled outside of inspec.

Say I pre-connected to vCenter before running Inspec which would then handle all the normal authentication options.

So then running inspec would just be something like "inspec exec ./profile -t vmware:// --vcpreauth"
