Martin Atkins 861ac536dd provider/template: convert resources to data sources

The template resources don't actually need to retain any state, so they
are good candidates to be data sources.

This includes a few tweaks to the acceptance tests -- now configured to
run as unit tests -- since it seems that they have been slightly broken
for a while now. In particular, the "update" cases are no longer tested
because updating is not a meaningful operation for a data source.
