This fixes instances where `zeek:see` was used incorrectly so it was not
rendered correctly. All these instances have been found by looking for
`zeek:see` in the generated HTML where it should not be visible anymore.
I also removed a doc reference to `paraglob_add` which never existed.
This caused confusion and I don't think it's very intuitive. If called
with a name that does not exist, this returns without a value, not even
an error value. Changing that seems like it could be more deprecation
work.

cluster: Be noisy when attempting to connect to an unknown node
Mostly due to spending too much time wondering why nodes didn't connect
when there was a mismatch between "manager" and "manager-1" in the
cluster layout. Remove manager from test-all-policy-cluster test to
avoid connection attempts in this test.
* topic/christian/disconnect-slow-peers:
Bump cluster testsuite to pull in Broker backpressure tests
Expand documentation of Broker events.
Add sleep() BiF.
Add backpressure disconnect notification to cluster.log and via telemetry
Remove unneeded @loads from base/misc/version.zeek
Add Cluster::nodeid_to_node() helper function
Support re-peering with Broker peers that fall behind
Add Zeek-level configurability of Broker slow-peer disconnects
Bump Broker to pull in disconnect feature and infinite-loop fix
No need to namespace Cluster:: functions in their own namespace
This adds a Broker-specific script to the cluster framework, loaded only when
Zeek is running in cluster mode. It adds logging in cluster.log as well as
telemetry via a metrics counter for Broker-observed backpressure disconnects.
The new zeek_broker_backpressure_disconnects counter, labeled by the neighboring
peer that the reporting node has determined to be unresponsive, counts the
number of unpeerings for this reason.
Here the node "worker" has observed node "proxy" falling behind once:
# HELP zeek_broker_backpressure_disconnects_total Number of Broker peering drops due to a neighbor falling too far behind in message I/O
# TYPE zeek_broker_backpressure_disconnects_total counter
zeek_broker_backpressure_disconnects_total{endpoint="worker",peer="proxy"} 1
Includes small btest baseline update to reflect @load of a new script.
This module is loaded by the telemetry framework, which we're now loading via
the cluster framework, i.e. also in bare mode. The resulting additional
thread (for creating reporter.log) trips up a number of btest baselines.
version.zeek doesn't use any of the string helper functions.
This adds re-peering at the Broker level for peers that Broker decided to
unpeer. We keep this at the Broker level since this behavior is specific to
it (as opposed to other cluster backends).
Includes baseline updates for btests that pick up on the new script's @load.

@Sheco reported that standalone epoch processing may exclude scheduled
events when the final sumstat epoch runs before. For example, this easily
happens when attempting to do sumstat observations within connection_state_remove().
Delay final epoch processing to zeek_done() instead.
This doesn't deal with the clustered version - this would need something
more elaborate and potentially a mechanism to delay the shutdown of
other cluster nodes until/after sumstat processing completed.
