Unable to create KeyVault backed variable group due to typing issues

[nmiodice]

When creating a KeyVault, we need to work with the following struct. I'm showing an abridged version here:

type VariableGroup struct {
	Name *string
	ProviderData *VariableGroupProviderData
	Variables *map[string]VariableValue
}

For most variable groups there is no problem. However, when creating a KeyVault backed variable group, the strict typing can become a challenge. There are 2 issues:

• VariableGroup.ProviderData needs to be configured as a *AzureKeyVaultVariableGroupProviderData
• Variables needs to be configured as a *map[string]AzureKeyVaultVariableValue

The lack of inheritence in Go requires the generated code to produce a VariableGroup that looks more like the following:

type VariableGroup struct {
	Name *string
	ProviderData interface{} // Maybe  pointer? Not sure...
	Variables map[string]interface{}  // Maybe  pointer? Not sure...
}

Note: We will need to be able to have this data in POST API calls as well as returned by the GET API call.
