MB-33971: System connections is bound to system port

There was a misunderstanding when the task to account for system
connections. I thought we wanted to account for all "couchbase
internal components", but ns_server have no control over the
connection usage for components like eventing, indexing, projector
query, fts etc, and we don't want to end up in a situation where
ns_server can't connect to the cluster because the pool of system
connections is consumed.

To work around this ns_server will mark an interface as "system"
and all connections towards that port is system connections.

MB-33599: Allow dynamic reconfig of interfaces

Add support for adding / deleting or changing network
interface descriptions. To simplify the implementation
all reconfiguration happens in the dispatcher thread
and not as part of reloading the config file.

To avoid ending up in a situation where we no longer
can connect to memcached changing the interfaces
works by first enabling all new interface descriptions,
and if no error happens it'll shut down the ones
no longer in the configuration.
