Consider what to do when WorkItem environment doesn't match environment of related entities

[jps1]

When running an analyzer (or any workitem) on one or more experiments, it's possible to run the SSMT workitem in a different environment than the entities that are being analyzed. This is by design, and idmtools will fall back on REST calls to get files, etc, and should generally work. However, this also makes it very easy to do accidentally, resulting in significantly slower performance, and possible other problems.

We should consider whether to somehow make this emit a warning, disable it by default while allowing a user to override when necessary, etc.

Need more investigation on this.
