fix reload issue by returning new configuration to the signal loop
example: run crowdsec, disable agent in the config file, reload config.
Now there is no agent but the signal loop believes there is, so
triggering a reload configuration again will make the process hang
forever.
This commit updates the configuration in the signal loop with the one
returned by the signal handler.
* github-ci: color unit test output and logs
* new config option: force_color_logs (useful in CI)
* bats: show sqlite/mysql dump at the end
* removed "-v" (print package names) from "go build"
* general workflow cleanup
