Description

Umbrella issue.

Solr should be a standalone application, where the main method is provided by Solr source code.

Here are the major tasks I envision, if we choose to embed Jetty:

• Create org.apache.solr.start.Main (and possibly other classes in the same package), to be placed in solr-start.jar. The Main class will contain the main method that starts the embedded Jetty and Solr. I do not know how to adjust the build system to do this successfully.
• Handle central configurations in code – TCP port, SSL, and things like web.xml.
• For each of these steps, clean up any test fallout.
• Handle cloud-related configurations in code – port, hostname, protocol, etc. Use the same information as the central configurations.
• Consider whether things like authentication need changes.
• Handle any remaining container configurations.

I am currently imagining this work happening in a new branch and ultimately being applied only to master, not the stable branch.
