I've split the Flow MediaWiki-Vagrant role into two, to make things simpler for casual Flow users.

If you don't have the Flow role enabled, you can stop reading now.

The basic 'flow' role will no longer depend on External Store and other optional dependencies.

You now need to do one of these things:

--- TLDR: If you use Flow on Vagrant regularly, enable wikimediaflow. Otherwise, enable externalstore or destroy your Vagrant. ---

* Enable 'wikimediaflow' (if you care about existing Flow content). This will bring in the optional dependencies again, and leave your content as-is.

* Enable 'externalstore' (if you care about existing non-Flow content that is using External Store already). Avoids the other optional dependencies, but brings in External Store, so existing External Store content can be read.

* Manually tweak configuration

* Just ignore the problems with old content

* Destroy and re-create your Vagrant (this will destroy the invalid content that points to no-longer-existing External Store, and leave you with a simpler config).
