With systems like docker swarm or docker compose it is usually a little awkward to manage secrets.
There is no way to directly inject them into the environment config. So you often have to write your secrets directly into the compose file
There are hacky workarounds such as overriding the entry-point of the container and loading a script which then fetches secrets from /run/secrets and replaces the environment variables, but this becomes very difficult once we are using docker images built from "scratch" (which is a really great practice otherwise) as there is no shell or standard tooling available
This adds a *_FILE variant of their Environment config values to work around this issue.

Some flags where unused and / or unnecessary as they are covered by alternatives implemented in PRs of milestone 0.15.0 and just complicated the setup.
closes#681
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`.
