give server class access to extra_config of create_vm

[Bonehead5338]

The intent of this PR is to give access to the extra_config parameter of create_vm method to the server class.

extra_config added in https://github.com/fog/fog-vsphere/pull/17

[Bonehead5338]

I mocked up some test code and checked this:

server.extra_config = {"disk.EnableUUID" => "TRUE"}`
server.save

result in created VM:

@ezr-ondrej updated per your comment, and per the VMware docs

I did a quick test and the results come back like below. Do we need to parse this back to a simple dictionary?
