Description

1. 1. 1. WHY
         1. need to show the latest PDX configuration to customer for check and validation
         1. need to know the latest PDX configuration, as an input for next updates

1. 1. 1. WHAT

1. 1. 1. Acceptance Criteria

• Scenario: show default config, configuration equals to runtimeInfo
• Scenario: show latest config, configuration does *NOT* equal to runtimeInfo

```gherkin
Scenario: show default config, configuration equals to runtimeInfo
Given REST API for Management is turned on on a cluster
AND A&A
AND a customer has permission of `CLUSTER:READ`
When the customer run [get] `management/v1/configurations/pdx`
Then he can find the latest configuration
```
