The script "makeGen3Skymap" has been changed to "butler register-skymap"

The register-skymap subcommand is defined in pipe_tasks (same as was).

Use butler register-skymap -h to see details about the new subcommand. The options and arguments are the same as makeGen3Skymap, and a new option --config was added to allow specifying config overrides using key-value pairs on the command line.

It was mentioned in the Jira ticket that this will probably affect @yusra and @hsinfang, so please take a look.

As always, we welcome feedback and requests about the command line interface & behavior, etc.
