Fix bug in Vagrantfile template related to WinRM options (missed quote)

[aleksey-hariton]

Setup of WinRM options breaks Kitchen, .kitchen.yml:

driver:
  name: vagrant
  winrm:
    username: Administrator
    password: password

Error:

/.../.kitchen/kitchen-vagrant/.../Vagrantfile:4: syntax error, unexpected tIDENTIFIER, expecting keyword_end

Reason: missed quote around WinRM values in Vagrantfile

Bump. Ran into this same issue and had to quote the winrm parameters twice ('"param"') as a workaround.

My only concern is with numeric or boolean values. However, ensuring all types are dealt with correctly is a more complicated change and this clearly makes the code better since most configs will be string based and are currently broken. Even numeric values like port are ok to pass in as a string I believe since all the way down to the protocol level they are treated as such. However timeout may be different where math is performed.
