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
```

Fix#64 (incompletely).
It's still not ideal. It makes more sense to use the gateway IP address of container network as outbound IP of cache server. However, this requires act to cooperate, some think like:
- act creates the network for new container, and returns the network to runner.
- runner extracts the gateway IP in the network.
- runner uses the gateway IP as outbound IP, and pass it to act as cache server endpoint.
- act It continues to create the container with the created network.
