closes#304 & #860
Dropped support for `DRONE_*` environment variables in pipeline steps. Pipeline meta-data can be accessed with `CI_*` variables.
- `CI_*` prefix replaces `DRONE_*`
- `CI` value is now `woodpecker`
- `DRONE=true` has been removed
The goal here is to make consistent use of configuration environment variables prefixed `WOODPECKER_`. Where several variants existed, this PR aims to remove all but one option, leaving the most explicit.
This PR only changes server and agent code, but not documentation, in order to keep the PR digestible. Once we have consensus that this is correct, I'll change docs accordingly.
User (rather: admin) facing changes in this PR:
- In general, support for all server and agent config environment variables (env vars) starting with `DRONE_` is removed. The according `WOODPECKER_*` variables must be used instead.
- The env var `WOODPECKER_HOST` replaces `DRONE_HOST`, and `DRONE_SERVER_HOST`.
- The env var `WOODPECKER_AGENT_SECRET` is used to configure the shared secret which agents use to authenticate against the server. It replaces `WOODPECKER_SECRET`, `DRONE_SECRET`, `WOODPECKER_PASSWORD`, `DRONE_PASSWORD`, and `DRONE_AGENT_SECRET`.
- The env var `WOODPECKER_DATABASE_DRIVER` replaces `DRONE_DATABASE_DRIVER` and `DATABASE_DRIVER`.
- The env var `WOODPECKER_DATABASE_DATASOURCE` replaces `DRONE_DATABASE_DATASOURCE` and `DATABASE_CONFIG`.
- move cli files from `cli/drone` to `cli/`
- move cli main to `cmd/cli/main.go` to match agent and server
- use version from `version/version.go` to match agent and server
