Dan Williams e085226f82 host-local: add DataDir IPAM conf option and use it for testcases
Add an e2e host-local plugin testcase, which requires being able
to pass the datadir into the plugin so we can erase it later.
We're not always guaranteed to have access to the default data
dir location, plus it should probably be configurable anyway.
