Credential leaking from class validation

[leehuwuj]

The hologram package is using jsonschema as validator tool to check class data fields. In the context of Dbt Profile class where password or api key is a field then if there is any wrong input the jsonschema will show all the instance value in plain text.

Example:
In the context of Dbt Redshift profile. If user forget to set the port parameter then the log will show up the password.

Traceback (most recent call last):
