(cherry picked from commit 54f2f28047)
When the controller relays requests to agents, we want agents to time out more
quickly than the corresponding controller requests. This allows agents to
respond with more meaningful errors, while the controller's timeout acts mostly
as a last resort to ensure a response to the client actually happens.
This dials down the table_expire_interval to 2 seconds in both agent and
controller, for more predictable timeout behavior. It also dials the agent-side
request expiration interval down to 5 seconds, compared to the agent's 10
seconds.
We may have to revisit this to allow custom expiration intervals per
request/response message type.
- 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.
