FR: method to scrub logs

[brobare]

Per slack conversation with @tbotnz opening a ticket to create an impelmention of "log scrubbing". Idea being, a method of removing certain patterns, such as usernme/password, from being presented in logs.

One idea on the implementation would be to allow for customized patterns to be matched:

{
    "scrub": [
         "password",
         "userrname",
         "some_special_key",
         "x-api-key"
    ]
}

We could use SecretStr from pydantic for this.
