Adding docker-compose test scenario for Splunk Enterprise with DFS.

Note that the following variables must be defined:

* SPLUNK_PASSWORD
* SPLUNK_LICENSE_URI (requires a license that includes DFS)
* SPLUNK_IMAGE (requires an image that includes this PR: splunk/splunk-ansible#194)

Example:

SPLUNK_PASSWORD=XXX SPLUNK_IMAGE=XXX SPLUNK_LICENSE_URI=XXX docker-compose -f 1sh1idx_dfs.yaml up -d
