Subject: [PATCH] feat(scripts): mainnet.sh (#3166)

Totally optional PR to add a `mainnet.sh` script that can be used to
start a consensus full node on mainnet. I'm using this to try to sync
from scratch with a celestia-appd binary built from `main`.

Example script output

```
root@rootul-mainnet-consensus:~/celestia-app# ./scripts/mainnet.sh
celestia-app home: /root/.celestia-app
celestia-app version: 1.0.0-rc0-564-g82703272

Are you sure you want to delete: /root/.celestia-app? [y/n] y
Deleting /root/.celestia-app...
Initializing config files...
Settings seeds in config.toml...
Downloading genesis file...
Starting celestia-appd in the background and piping logs to mainnet.log
You can check the node's status via: celestia-appd status
```
