Set the default environment

[lkngtn]

🚀 Feature

When using the CLI to interact with organizations using the dao commands its often the case that you want to interact with the same organization repeatedly.

In practice this means appending --environment aragon:rinkeby to all of the commands which can be a bit of a pain.

It would be nice to be able to specify the default environment once then use that unless otherwise specified by a flag.
