request: make `list` similar to `session` e.g. show instance-ids that match a specific tag

[nitrocode]

Context

I like the usage of this command. I have 10 instances that match this tag and session will ssh/ssm into one of the instances perfectly.

$ aws-gate session Name:my-app

But what if I wanted to ssh/ssm into a specific instance? I cannot easily do this unless I list my instances using the awscli.

$ aws ec2 describe-instances \
  --filters "Name=tag:Name,Values=my-app" \
  --query 'Reservations[].Instances[].InstanceId'

Proposal

What I'd like is something like this and have it populate all the instance ids that match it.

$ aws-gate list Name:my-app

It would be perfect if it worked for multiple tags too

$ aws-gate list Name:my-app,env:prod

Thank you!
