feat: spartan token transfer

[just-mitch]

Adds prover node and metrics to the k8s helm chart.
Adds a test that transfers tokens privately.
Create a new CI action for creating a k8s cluster and running the test.

Benchmark results

Metrics with a significant change:

• proof_construction_time_sha256_30_ms (16): 1,746 (+27%)
• avm_simulation_time_ms (Token:transfer_public): 19.1 (-39%)

Detailed results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.

Looks great! Love the use of initContainers to deploy L1 contracts before starting the node

[alexghr]

❤️ 🔥

Do otlp/jaeger/grafana all run on the same pod? 🤔

[just-mitch]

Presently, yes they do for simplicity. They'll likely be split out in the future- I didn't see an immediate need to do so.
