shield create-store does not ask AWS information when creating store in s3[BUG]

[xiujiao]

Describe the bug
When I run shield create-store, I went through the following steps

shield create-store
Store Name: test
Description: to store backup for stuff
SHIELD Agent (IP:port): x.x.x.x:5444
Backup Plugin: s3
Threshold: 5G

It did not ask me information on AWS key ID and secret and bucket name, caused the store to fail after being created.
I was able to run shield update-store to add those missing entries and the store did work after that.

To Reproduce
shield create-store with s3 plugin

Expected behavior
It should ask information on S3 authentication and bucket since it is required to make the store work

This is a "works as designed" part of the SHIELD CLI; Perhaps the better approach is to remove the semi-interactive form and just rely on command-line parameters for everything.
