Clean up features

Factoring things out has moved our dependencies a bit, making
odl-netconf-util and odl-netconf-ssh dead features.

This renames odl-netconf-util to odl-netconf-mdsal-common, carrying a
dependency on mdsal-dom-api. We package netconf-mdsal-common and
netconf-dom-api here.

We then drop netconf-auth from odl-netconf-api, as it really is a thing
specific to the auth plugin.

Registering ServerSseHandler into Netty's pipeline is:
- preventing us to implement another SSE based web resources,
for example those needed for subscribed notifications.
- adding performance drawback as ServerSseHandler is invoked
on every GET request.

Migrate HttpClientServerTest

Use HTTPServerSession for test harness, as we are entering a phase where
mocking would have to duplicate production code.

Since we are using HTTPServerSession, we can verify our task gets
executed on the corresponding virtual thread. That in turn allows us to
ditch the executor service in favor of an explicit sleep.

Split out CleartextUpgradeHandler

The code structure is clear: we have two handlers:
- AlpnUpgradeHandler handles the transition from TLS for HTTPS
- CleartextUpgradeHandler handles the transition frop TCP for HTTP

Split out the anonymous class into a named entity, so we have an
improved debugging experience -- including transition debug messages.

We also talk to our superclass to not automatically release the message,
and therefore we do not need to undo its work in channelRead().

Fix cleartext HTTP/2 upgrade

HttpServerUpgradeHandler is a HttpObjectAggregator, therefore we need to
pass a consistent maximum request size -- otherwise it will reject the
first HTTP/1 request.

The second part of the puzzle is intercepting the first request: for
this we already have a an UpgradeEvent hook.

Refactor HTTPScheme.initializeServerPipeline()

The split nature of setup makes it quite unclear as to what is going on.

This improves the code flow, as we now understand that channelHandler()
is a HTTP2->HTTP1 thing -- hence we can allocate it only when needed.
This leads to TLS-based-HTTP1 not allocating it at all.
