bandit scan results post secret value in findings

[vpaturi]

The scan results from bandit , when they detect secrets will post the secret value into finding.
This is a feature request to make sure such secret value is not logged into the report for bandit.
example:

bandit-B105-2119	B105	Possible hardcoded password: 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY'
bandit-B105-3562	B105	Possible hardcoded password: 'super_secret_password_123'
