Migration of njs to node container (gateway)

[phantomjinx]

• Update of git actions to reflect second image

• Upgrade of yarn to 4.3.1

  • not necessary and could be broken out if too confusing

• Upgrade of node to version 20

  • whether we should go whole way to version 22 ?

• Hawtio-Online Docker file renamed to Dockerfile-nginx

• Addition of Dockerfile-gateway for buidling of gateway image

• Inclusion of hawtio-403.html page ** Locations in nginx are now localhost-only rather than internal so can try them but will return a 403 error

• Makefile updated to include build of gateway image

• deploy/Makefile update to include install of gateway image

• docker/gateway project for the gateway image Express server with proxying capabilities to master (required due to websockets) Unit tests migrated from njs testing Logging with pino Development build with tsup Production build with webpack (switched from tsup due to persistent bundling errors) js-yaml replaced with yaml and imported as dependency ** jwt-decode imported as dependency

• HAWTIO_ONLINE_GATEWAY_APP_PORT exposed as env var allowing users to change running port if required (maybe not required in production but only in development)

• root package.json commands updated to consider docker/gateway

A review of 60 files may not be the easiest solution so if anyone would like to suggest an alternative then happy to accommodate.

Am sure there are issues so although a PR, lets consider this a working PR that I'll continue to update until all concerns met.
