Rewrite of the UI using Typescript, Vue3, Windicss and Vite. The design should be close to the current one with some changes:
- latest pipeline in a sidebar on the right
- secrets and registry as part of the repo-settings (secrets and registry entries shouldn't be used as much so they can be "hidden" under settings IMO)
- start page shows list of active repositories with button to enable / add new ones (currently you see all repositories and in most cases you only add new repositories once in a while)
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`.
