Deploy from root

[mgyucht]

Changes

V0.1.1 can't be depended upon directly for some reason. I suspect this is because I'm running mvn deploy from the databricks-dbutils-scala subdirectory. Trying again, this time from the parent directory after moving some information to the top-level.

Separately, we need a dummy release module for the nexus staging plugin. See the docs about skipNexusStagingDeployMojo in https://help.sonatype.com/repomanager2/staging-releases/configuring-your-project-for-deployment:

Set to false by default, this flag will cause to skip any execution of the deploy goal of the plugin when set to true similar to maven.deploy.skip. In multi-module builds the staging of all components is performed in the last module based on the reactor order. If this property is set to true in the module, all staging will be skipped. You have to ensure that this property evaluates as true in the last module of the reactor. If necessary, you can add a dummy module.
