Feature Request: Tab-completion for bash, zsh & powershell

[markbate]

At the moment, the ask cli only has a few sub-commands, but that will grow over time.
We should make it easier for developers to find commands & parameters by offering tab completion, similar to that of the aws cli.

I don't have stats on which shells developers are using, but I would think providing this functionality for bash, zsh & powershell would cover the majority of skill developers. We can support more exotic shells if/when we see requests for them.
