Feature request: retrieve temp password token by executing command

Our org recently switched to using ADFS IAM authentication for our Aurora Pg credentials. This means we don't have a static, saved password any more, but we have to get credentials on the fly via something like:

export RDSHOST="mypostgres-cluster.cluster-123456789012.us-west-2.rds.amazonaws.com"
export PGPASSWORD="$(aws rds generate-db-auth-token --hostname $RDSHOST --port 5432 --region us-west-2 --username jane_doe )"

It would be great if TablePlus could run a script to retrieve the password, so we don't have to do it manually every time.

(While less important, this would be useful for the hostname, too. AWS IAM ADFS doesn't support CNAMEs for clusters yet, so while rare, it's possible for the dynamic hostname to change as well.)

This would be really helpful for those of us on Azure Cloud as well who utilize security groups via IAM to authorize user access.

This would also be very helpful for us a Lenus eHealth

I believe it should support dynamic usernames as well so it could be used with Hashicorp Vault.

TablePlus now supports getting the password via Command Line IAM.

if you have a chance, please try this patch: https://www.dropbox.com/s/3rkgc4yylrr9buj/TablePlus.dmg?dl=0 Please let me know if you're seeing any issue.

@huyphams sorry to comment on a closed PR; is it possible to not hide the password input, when the type is Command Line?
