Expand properties for collected resource information

[BernieWhite]

For PSRule for Azure to evaluate many rules properties must be able to be inspected for each resource. For example:

The property properties.sslEnforcement need to be inspected to determine if it set to Enabled.

# Synopsis: Enforce encrypted PostgreSQL connections.
apiVersion: github.com/microsoft/PSRule/v1
kind: Rule
metadata:
  name: Azure.PostgreSQL.UseSSL
  ref: AZR-000147
  tags:
    release: 'GA'
    ruleSet: '2020_06'
    Azure.WAF/pillar: 'Security'
  labels:
    Azure.ASB.v3/control: 'NS-2'
spec:
  type:
  - Microsoft.DBforPostgreSQL/servers
  condition:
    field: properties.sslEnforcement
    equals: Enabled

Currently the get API only retrieves the resource itself without the properties property.

Because we need to do this based the resource provider API version I propose we:

• Get each resource provider API version.
• Get each resource via resource ID using the latest API version reported by the resource provider.

Thoughts?

• PSRule state showing Fail, not Pass for PostgreSQL encryption Azure/PSRule.Rules.Azure#1914
• Azure.AppService.UseHTTPS reports fail although app service is deployed with https only Azure/PSRule.Rules.Azure#1919

AzGovViz / PSRule integration under review. Findings and decision on how to proceed will be posted soon. Closing for now.
