This addresses feedback to GH-1814. The most significant change is the
fact that the ChipertextRecord now can remain &transient - which might
lead to improved speed.
* topic/christian/controller-renaming:
Bump external cluster testsuite to reflect Management framework reorg
Bump zeek-client to reflect Management framework reorg
Reorg of the cluster controller to new "Management framework" layout
- 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.

Mostly trivial changes, except for one aspect: if a module exports a record type
and that record bears Zeekygen comments, then redefs that add to the record in
another module cannot be private to that module. Zeekygen will complain with
"unknown target" errors, even when such redefs have Zeekygen comments. So this
commits also adds two export-blocks that aren't technically required at this point.
* topic/christian/cluster-controller-get-nodes:
Bump external cluster testsuite
Bump zeek-client for the get-nodes command
Add ClusterController::API::get_nodes_request/response event pair
Support optional listening ports for cluster nodes
Don't auto-publish Supervisor response events in the cluster agent
Make members of the ClusterController::Types::State enum all-caps
Be more conservative with triggering request timeout events
Move redefs of ClusterController::Request::Request to their places of use
Simplify ClusterController::API::set_configuration_request/response
This allows querying the status of Zeek nodes currently running in a cluster.
The controller relays the request to all instances and accumulates their
responses.
The response back to the client contains one Result record per instance
response, each of which carrying a ClusterController::Types::NodeState vector in
its $data member to convey the state of each node at that instance.
The NodeState record tracks the name of the node, its role in the controller (if
any), its role in the data cluster (if any), as well as PID and listening port,
if any.
This makes cluster node listening ports &optional, and maps absent values to
0/unknown, the value the cluster framework currently uses to indicate that
listening isn't desired.
This commit changes DPD matching for TLS connections. A one-sided match
is enough to enable DPD now.
This commit also removes DPD for SSLv2 connections. SSLv2 connections do
basically no longer happen in the wild. SSLv2 is also really finnicky to
identify correctly - there is very little data required to match it, and
basically all matches today will be false positives. If DPD for SSLv2 is
still desired, the optional signature in policy/protocols/ssl/dpd-v2.sig
can be loaded.
Fixes GH-1952
