All these files can be generated using the `make api` command and there
is no real need to commit these into the repo. Only the api/go files
need to be comitted of how the Go import system works.
This also updates the Rust, Go, JS and gRPC-web (JS) code generation and
UI build to use the nix-shell environment instead of using Docker.
This crate can be used to build external ChirpStack integrations.
The plan is to move all non-HTTP based integrations to external
repositories. The reason is that these integrations usually require
quite some external dependencies as these rely on their own SDKs.
This reduces the number of external services that must be running to
succesful run 'cargo test'. In this case one the requirements that
ChirpStack has must be present and there is no need to run local
Kafka and RabbitMQ instances.
These integrations can still be tested using the 'test-all-integrations'
feature flag (which is included in the CI workflow).
With the update to diesel 2.0.0-rc0, it is now possible to cross-compile
without emulation. Note that during each (cross)compile, we have to
install libpq-dev for the target platform, as only one version can be
installed at a time (e.g. libpq-dev:amd64 conflicts with libpq-dev:armhf).
