Proposal: Add fig autocomplete support

[imxw]

Description

I've been using the command line for a long time, and I'm a user of fig autocomplete which is very cool. It lets you add visual autocomplete to any CLI tool or script. If dtm supports fig autocomplete, I believe it will greatly improve the user experience.

This idea sounds cool! I agree to add this feature.
I don't know what others think @devstream-io/pmc ;
If everybody agree, I suggest to assign this feature to @imxw implement.

fig looks nice. Please also consider alternatives like bash-completion, examples:

• https://kubernetes.io/docs/tasks/tools/included/optional-kubectl-configs-bash-linux/
• https://kubernetes.io/docs/tasks/tools/included/optional-kubectl-configs-bash-mac/

Make a decision using your best judgement :)

A document with "how to use fig along with dtm" is needed.

What to pay attention to when writing documents now?
