ci/cd refactor: on-pr workflow

[jgreat]

Motivation

Refactoring ci/cd workflows. First steps on-pr workflow.

• linters: rust, helm, docker, actions
• Run Tests
• Build code for testnet/mainnet
  • MacOS (arm64, x64)
  • Linux (x64)
• Build Linux containers and publish to dockerhub
• Build helm charts and publish to harbor

Each build step caches results so compiles should only happen on rust/cargo changes.
Each Run will create a set of artifacts. Zip files with binaries in the GH Actions interface and Container/Charts in their respective repos.

Next steps

• on-tag workflow for publishing tagged binaries, containers and creating the github release.
• enhance builds with Linux ARM64 artifacts
• Integration testing for full-service against mainnet/testnet networks.
• Clean up/standardize repo shell scripts so they will pass shellcheck linting.
