Ensure backoffMillis is not less than expected

Keeping the last backoff value after randomization can
reduce the SleepingTask timeout to a much smaller value
than expected.

Fix this by keeping the backoff value before randomization.

Robert Varga [Tue, 1 Oct 2024 17:05:57 +0000 (19:05 +0200)]
Refactor RESTCONF request dispatch

The act of servicing an HTTP request has four distinct phases:
- request validation and binding, synchronous
- request execution, asynchronous
- result interpretation, synchronous
- result streaming, asynchronous

We have first two cobbled together in RestconfRequestDispatcher, while
the last two are handled synchronously in ResponseUtils and the various
RestconfRequest subclasses.

This patch tackles the problem in RestconfRequestDispatcher, separating
the two phases.

We introduce a prepare() method, whose sole raison d'etre is to
synchronously process the contents of HttpRequest, i.e. method, URI and
headers, so as to arrive at a specific request (and its parameters) that
we want to be executing.

The result is communicated via PreparedRequest, which is a sealed
interface with two specializations:

1. CompletedRequest, holding an immediate result -- typically an error
   response, or a response that is statically known (such as the answer
   to 'OPTIONS /restconf/operations HTTP/1.1')
2. PendingRequest, represents has a number of specializations for the
   various requests we can execute asynchronously

The former is handled by immediate conversion to a FullHttpResponse,
which is then sent to the client. The latter is then fed any request
body, if present and executed, with the results processed in the usual
way.

We also eliminate two implementation hotspots:

1. RequestParameters, which has comindled the various request-related
   concerns in a structure-like blob. We now track the various
   parameters in the various AbstractPendingRequest subclasses, keeping
   them colocated with their users.

2. ResponseUtils along with the message builder -- which are now
   replaces through the Response interface, which offers decoupling of
   response shapes from how they map to HTTP constructs -- which is
   really a pipeline-side concern.

The result is that we have separated out the concerns, so that each
processing stage has a natural view of what it needs to handle --
resulting in much more modular codebase, where individual concerns can
be further evolved without touching others.

Most significantly, the process of turning RestconfServer responses
into ByteBufs is driven completely from PendingRequestListener -- i.e.
fully at the discretion of the Netty pipeline side of the house.
