Added new BIND_LOG environment variable. By default you still have -g, however you can now override directly with -f for foreground logging. The README also has a detailed section on logging practices. I've also updated the binary version to the latest Alpine image v3.11.3

## How do I just change Bind STDERR to STDOUT logging?
There is now a "BIND_LOG" ENV (environment) variable for logging
Environment variables can both have a default and be customized at run time.
```
"-g" = (default) Run the server in the foreground and force all logging stderr.
"-f" = Run the server in the foreground
```
For more information, see: https://www.slideshare.net/MenandMice/bind-9-logging-best-practices
By default, the "-g" value is set, as that logs all to STDERR.
You can now override it with "-f" by passing `-e "BIND_LOG=-f"` to `docker run`
