Test suite execution for v4.2.3 and v4.2.4 fails due to not parsing the config properly

[AbhishekBandarupalle]

Hi,

I encountered an issue where the testsuite is unable to load the config:

�[36mINFO   �[0m[May 18 17:55:51.344][utils.go: 50] Loading config from file: /usr/tnf/config/tnf_config.yml 
�[31mFATAL  �[0m[May 18 17:55:51.344][provider.go: 202] Cannot load configuration file: yaml: unmarshal errors:
  line 6: cannot unmarshal !!seq into map[string]string 

I followed the syntax as per the latest release and here's a DCI job for the test run:

Also, I was able to get a successful run when I used the deprecated format for tnf_config.yaml
Here's a successful run:

Can you please retry with 4.2.4. There is a bug with the 4.2.3 format.

I had the same issue with 4.2.4 -- It was then I tried 4.2.3
