Minor issues in helloworld-ssl, helloworld-mutual-ssl and helloworld-mutual-ssl-secured readme

1. There are multiple mentions of 'widlfly' in productised quickstart.
2. Result for configure-ssl.cli script file is wrong. Readme file states:

The batch executed successfully

The actual output is

The batch executed successfully
process-state: reload-required 

3. Snippet from configuration files in Review the Modified Server Configuration bullet 1 is not the same as configuration in actual standalone.xml file.
