Closed Feature: Allow specification of which servers to run AppFabric on [20965]

Would be nice if a flag would be added to the XML where I can specify on which SharePoint 2013 servers to run the AppFabric service. This could then translate in providing the -SkipRegisterAsDistributedCacheHost flag when running the Connect-SPConfigurationDatabase or New-SPConfigurationDatabase cmdlet to avoid having AppFabric installed on the SharePoint 2013 machine. When not specifying anything, it will install AppFabric on each SharePoint 2013 machine.
Comments: Resolved with changeset 108460: Changes in this release:

- Fixes for AddToHOSTS function to skip adding local computer name to HOSTS file (issue 19998) and to avoid including path info in the HOSTS file entry in cases where host-named site collections are used (issue 20932)
- Check for and if necessary remove trailing slash from the data directory (issue 20884)
- Updated ConfigureFarmAdmin function to add Farm Account to local admins (temporarily) if either explicitly requested, or if either user profile service app or distributed cache is being provisioned on local server (per @harbars)
- Updated CreateOrJoinFarm function to leverage -SkipRegisterAsDistributedCacheHost switch when joining/creating farm and be more verbose
- Updated AutoSPInstallerInput.xml to use "CONTOSO" for the domain of sample accounts, and proper FQDNs for URLs - makes search & replace easier and discourages using http:// (i.e. localhost) for URLs
