* Refactor Block/Header definition
Refactor block/header definition so that it's now responsibility
of the nomos-core crate. This removes definitions in ledger/consensus
crates since there's no need at that level to have an understanding
of the block format.
The new header format supports both carnot and cryptarchia.
* Prometheus container and configuration for testnet
* Add graphana related configuration and container
* Use metrics feature in testnet nodes
* Grafana configuration files and datasources
* A wrapper crate for prometheus client
* Initial integration of metrics for mempool
* Merge mempool metrics imports
* Add cli flag to enable metrics
* Add nomos metrics service for serving metrics
* Use nomos prometheus metrics in the node
* Rename metrics to registry where applicable
* Expose metrics via http
* Featuregate the metrics service
* Style and fail on encode error
* Add metrics cargo feature for mempool
* Make chat messages unique
Since DA will rightfully ignore duplicated messages, we need to add a nonce to make sure
every message is unique, so that a user can send the same message twice.
This nonce is randomly generated for simplicity.
* Clear in_flight status upon error on chat app
* Add chat demo for testnet
This commit adds a simple demo to showcase the capabilities of the
Nomos architecture. In particular, we want to leverage the DA
features and explore participants roles.
At the same time, we're not ready to commit to any speficic format
or decision regarding common ground yet.
For this reason, we chose to implement the demo at the Execution
Zone (EZ) level.
In contrast to the coordination layer, each execution
zone can decide on its own format, which allows us to experiment
without having to set a standard.
The application of choice for the demo is an (almost) instant
messaging app where the messages are broadcast to the public by
leveraging the full replication data availability protocol.
In this context, the cli app acts as a small EZ disseminating
blobs, promoting blob inclusion and updating its state (i.e. list
of exchanged messages) upon blob inclusion in the chain.

* Use value instead of variable in .env.testnet
* Reduce testnet logs verbosity
Debug logs are too verbose for long running node instances. If needed
users could manually adjust configuration in `testnet/*_config.yaml`
files without rebuilding the docker images.
