Fixes#7299 where it was found that computer_name is not optional (as
the msdn documentation states)

adminPassword
Reports from issues showed the following errors:
```
{
"error": {
"code": "InvalidParameter",
"target": "adminPassword",
"message": "The supplied password must be
between 6-72 characters long and must
satisfy at least 3 of password complexity
requirements from the following: \r\n1)
Contains an uppercase character\r\n2)
Contains a lowercase character\r\n3)
Contains a numeric digit\r\n4) Contains a
special character."
}
}
```
This commit adds some documentation for the adminPassword complexity
requirements
ssh_keys were throwing an error similar to this:
```
* azurerm_virtual_machine.test: [DEBUG] Error setting Virtual Machine
* Storage OS Profile Linux Configuration: &errors.errorString{s:"Invalid
* address to set: []string{\"os_profile_linux_config\", \"0\",
* \"ssh_keys\"}"}
```
This was because of nesting of Set within a Set in the schema. By
changing this to a List within a Set, the schema works as expected. This
means we can now set SSH Keys on VMs. This has been tested using a
remote-exec and a connection block with the ssh key
```
azurerm_virtual_machine.test: Still creating... (2m10s elapsed)
azurerm_virtual_machine.test (remote-exec): Connected!
azurerm_virtual_machine.test (remote-exec): CONNECTED!
