dig txt version.sslip.io returns version

Browse Source 
I needed a way of determining the version that a server was running. I
orginally considered a command-line argument, but then I thought, "Why
not create a DNS record for it? That way I can query running servers
without needing to ssh onto the machine."

The TXT record consists of three distinct strings: version, compile
date, and git hash.

```bash
dig txt version.sslip.io +short
    "2.2.1"
    "2021/10/03-15:08:54+0100"
    "6a928eb"
```
