Add ability to control name of config file via environment variable

[iilyak]

Use case

For development in docker there might be a need to have different set of tasks. One set of tasks to run on a host system and another one inside docker container.

Proposal

Implement support for ALFRED_FILE_NAME variable to override hardcoded alfred.yml. In this case the one would be able to define Docker environment variable ENV ALFRED_FILE_NAME alfred.docker.yml.

This is an interesting feature. Not sure when I can get to it.

Having said that, I use arguments in combination with ok, fail and golang templating to solve all the issues and none of mine have been too hairy.

This ended up being trivial. You can use the -f flag(I documented it in the readme). By default, I'm looking for alfred/alfred.yml or some variation of alfred.

You can use the -f flag now. So if you did alfred -f bleh task.to.run we'd look for bleh.yml or bleh/*.bleh.yml

Thank you.
