Issue
This is a fix for issue #2689. The reason is that the blspass read from stdin when "-blspass std" is specified and it conflict with aws setting (which also read from stdin) reading required for aws encrypted bls key.
Test
Tested both "-blspass std" and "--aws_blskey " works. Note that only one way of reading from stdin is supported. Either for blspass or for aws credentials.
