Jason Song 7e7096e60b Refactor environment variables to configuration and registration (#90)
Close #21.

Refactor environment variables to configuration file (config.yaml) and registration file (.runner).

The old environment variables are still supported, but warning logs will be printed.

Like:

```text
$ GITEA_DEBUG=true ./act_runner -c config.yaml daemon
INFO[0000] Starting runner daemon
WARN[0000] env GITEA_DEBUG has been ignored because config file is used

$ GITEA_DEBUG=true ./act_runner daemon
INFO[0000] Starting runner daemon
WARN[0000] env GITEA_DEBUG will be deprecated, please use config file instead
```
