Issue details

Currently, when calling esc env set ... --secret, the secret value needs to be provided via the CLI. This is a problem because on MacOS and Linux, the whole command is stored in the shell history file and in plain text.

Like pulumi config set --secret, it would be great if this CLI could support the following ways to provide a value .

• cat file.txt | esc env set aws-ts-demo-with-policy apiKey --secret
• esc env set aws-ts-demo-with-policy apiKey --secret < file.txt

Affected area/feature

• config
• secret

I'm not sure if there's a supported way to read from stdin yet, but you can already set the values via a prompt if you use esc env edit <env name>.

I do like the idea of having a per-value prompt for secrets as well. I'm going to open a separate issue for that feature to make sure we don't lose this feedback.
