add kernel experiment (#10820)

[IanMatthewHuff]

Porting my addition of the experiment for ZMQ from ds/rawKernel into master. Experiment needs to be in master so that it gets downloaded and cached. Then I can actually use the experiment in the ds/rawKernel branch.

• Pull request represents a single change (i.e. not fixing disparate/unrelated things in a single PR).
• Title summarizes what is changing.
• Has a news entry file (remember to thank yourself!).
• Appropriate comments and documentation strings in the code.
• Has sufficient logging.
• Has telemetry for enhancements.
• Unit tests & system/integration tests are added/updated.
• Test plan is updated as appropriate.
• package-lock.json has been regenerated by running npm install (if dependencies have changed).
• The wiki is updated with any design decisions/details.

This is just a port of the experiment that I added in ds/rawKernel to master. Same issue as @rchiodo was hitting in that it needs to be in master so that I can actually use / reference it.
