Review quickstart README metadata to optimize it for the Google search

See JDF-787.

The jboss.org development team plans to do the following:

Parse the first line of each README file to remove the quickstart name prefix and use the rest for Google SEO title. That field is limited to ~55 characters.
Use the 'Summary:' metadata for the description. This field is limited to 155 characters.

This information is what shows up on the search result page, so the better it better describes the example.

I went through all the JBoss EAP quickstart README files to shorten the title and lengthen the Summary to be more descriptive. We need to do this for all of the other quickstarts, including:
