Cardano Updates

Introduces 'Cardano.Node.Configuration.Leios.LeiosDbConfig' with two
constructors:

  - LeiosDbInMemory          (matches 'LeiosDbConnection's in-memory backend)
  - LeiosDbSQLite !FilePath  (SQLite backend, file relative to node CWD)

Wired through 'PartialNodeConfiguration' / 'NodeConfiguration' as
'ncLeiosDbConfig' with JSON parsing ('"LeiosDbConfig":{"Backend":...,
"Filepath":...}') and a default of 'LeiosDbSQLite "leios.db"'.

At node startup ('Cardano.Node.Run.handleSimpleNode'), the configured
backend is materialised into a 'LeiosDbHandle' (via 'newLeiosDBInMemory'
/ 'newLeiosDBSQLite') and passed into 'RunNodeArgs' through a new
'rnLeiosDb :: Maybe (LeiosDbHandle m)' field, which consensus's
'runWith' threads into the Leios kernel's shared connection.
'Nothing' falls back to the in-memory default.

The consensus Leios chunks added four fields to the consensus tracer
records that cardano-node assembles in 'Cardano.Tracing.Tracers' (old
style) and 'Cardano.Node.Tracing.Tracers' (new style):

  - Consensus.Tracers'      gained 'leiosKernelTracer' and 'leiosPeerTracer'
  - NodeToNode.Tracers'     gained 'tLeiosNotifyTracer' and 'tLeiosFetchTracer'

This commit populates those fields in both 'mkTracers' code paths so
the record-construction sites are total. All four are wired to
'nullTracer' for now; the corresponding 'Transformable' / 'MetaTrace'
instances and EKG metrics are left as TODO. The new-style tracing
system will accordingly emit a 'TracerConsistencyWarnings' for the
four Leios namespaces declared in the config.yaml — that surfaces the
gap explicitly rather than silently dropping the configuration.

Adds the corresponding selectors to 'TraceSelection' / 'PartialTraceSelection'
and their JSON parsing:

  - traceLeiosKernel          / Consensus.LeiosKernel
  - traceLeiosPeer            / Consensus.LeiosPeer
  - traceLeiosNotifyProtocol  / LeiosNotify.Remote
  - traceLeiosFetchProtocol   / LeiosFetch.Remote

Also drops the duplicate 'LogFormatting (Simple/Stateful.TraceSendRecv)'
and 'MetaTrace (Simple/Stateful.TraceSendRecv)' instances that the
upstream leios-prototype branch carried in
'Cardano/Node/Tracing/Tracers/NodeToClient.hs' — they are now provided
by 'ouroboros-network:framework-tracing' and would collide if redefined
here.

The consensus Leios chunks extended 'NTN.Codecs' with two extra type
parameters ('bLN' / 'bLF', for LeiosNotify and LeiosFetch), and the
network-side BearerBytes/Reception work changed 'runPeerWithLimits' to
return 'Maybe (Reception bytes)' (instead of 'Maybe bytes') and made
'byteLimitsKeepAlive' parameter-less.

Update 'tx-generator' to compile against the rebased stack:

  - Pull in 'ouroboros-network:framework-tracing' as a sublib dependency.
  - Extend the local 'myCodecs' type to 9 'ByteString' parameters (was 7).
  - Update 'kaClient' return type to 'IO ((), Maybe (Mux.Reception ByteString))'.
  - Drop the size-function argument from 'byteLimitsKeepAlive'.

Both had been on the leios-prototype and and need to be re-exposed after
resetting to a recent cardano-node version.

Only the rest-in-mempool execution units metric was not easily
applicable. That part of the code will change anyways though.

Updates cabal.project to point at the three rebased Leios forks that
ship with this cardano-node 11.0.1 build:

  - ouroboros-consensus  @  IntersectMBO/ouroboros-consensus
    branch leios-prototype-remake-3.0.1.0
    Single squashed Leios commit on top of release-3.0.1.0
    (mempool + diffusion + chain inclusion + voting + demo).
  - ouroboros-network    @  IntersectMBO/ouroboros-network
    branch leios-prototype-remake-1.1.0.0
    Three Leios commits on top of ouroboros-network-1.1.0.0
    (BearerBytes, Reception arrival-time, drop unused imports)
    + a trace-dispatcher version bump for compat with cardano-node 11.0.1.
  - cardano-ledger       @  IntersectMBO/cardano-ledger
    branch leios-prototype-remake
    Adds 'Maybe LeiosCert' on the Dijkstra block body
    (Dijkstra-only, mirrors 'Maybe PerasCert').

Also drops the 'dmq-node' extra-package (its latest CHaP release
requires ouroboros-network:framework-tracing, a sublib name that
the remade network fork doesn't carry).

Vendors a one-line 'ekg-forward' source patch (left untouched here)
to match the network's pre-bump 'ConnectToArgs' shape.
