Support bundling of LCF with an app

It should be possible for an application developer to bundle LCF with an application to facilitate installation and deployment of the application in conjunction with LCF. This may (or may not) be as simple as providing appropriate jar files and documentation for how to use them, but there may be other components or scripts needed.

There are two options: 1) include the LCF UI along with the other LCF processes, and 2) exclude the LCF UI and include only the other processes that can be controlled via the full API.

The database server would be included.

The web app server would be optional since the application may have its own choice of web app server.

One use case is bundling LCF with Solr or a Solr-based application.

Note: This issue is part of Phase 2 of the CONNECTORS-50 umbrella issue.
