[Refactor] Revisit devtools Commands, Groups and Organization

[terrancedejesus]

Summary

The devtools.py library was originally meant to house CLI commands related to Detection Rules releases.

@root.group('dev')
def dev_group():
    """Commands related to the Elastic Stack rules release lifecycle."""

Over time, additional CLI commands have been added that are not related to the release. We should revisit these commands and groups to determine appropriate naming, functionality, grouping, etc. There is also code related to Kibana pushes for release which we no longer do that could be removed.
