Up to now, agents and controllers listened locally only, and the Supervisor
(which listens when we run an agent) listened globally. It's now the other way
around: controllers and agents listen globally and the Supervisor, when
listening, does so locally.
This allows specifying spool and variable-state directories specifically for the
management framework. They default to the corresponding installation-level
folders.
- This gives the cluster controller and agent the common name "Management
framework" and changes the start directory of the sources from
"policy/frameworks/cluster" to "policy/frameworks/management". This avoids
ambiguity with the existing cluster framework.
- It renames the "ClusterController" and "ClusterAgent" script modules to
"Management::Controller" and "Management::Agent", respectively. This allows us
to anchor tooling common to both controller and agent at the "Management"
module.
- It moves common configuration settings, logging, requests, types, and
utilities to the common "Management" module.
- It removes the explicit "::Types" submodule (so a request/response result is
now a Management::Result, not a Management::Types::Result), which makes
typenames more readable.
- It updates tests that depend on module naming and full set of scripts.
