Fix VM password restrictions

[djberg96]

This fixes the VM password restrictions to match the actual Azure password restrictions for virtual machines. The rules are that the password must at least 12 characters long and match at least 3 of the following 4 conditions:

• Contain 1 lowercase character
• Contain 1 uppercase character
• Contain 1 number
• Contain 1 special character

@djberg96 - I don't think a minimum of 12 characters meets the requirements:
