[ISSUE]Cannot update carbon.properties file with new configuration model

[denuwanthi]

Describe the issue:
If we want to update the property value in carbon.properties file, there is no proper way of doing it using the new configuration model.

How to reproduce:
1.Add following configuration to deployment.toml file
[system.parameter]
'org.wso2.CipherTransformation'="AES"

2.Start the server. Still the original value will be picked up.

3.Restart the server. Now the new value in the deployment.toml will be picked.

Expected behavior:
Once you change the deployment.toml, that value should be fixed from first server start up onwards.
