Adding Redacted Keys

[clr182]

Goal

Filtering config option is case sensitive and is no longer in line with our notifier spec; as such it should be deprecated in favour of redactedKeys.

Design

Added redactedKeys configuration option, which is case insensitive, as a replacement for the filters configuration option. Additionally due to conflictions the default filters parameters were changed.

Changeset

• Added redactedKeys config option.

• Made redactedKeys case insensitive.

• Changed filters config default parameters from {"password", "secret", "Authorization", "Cookie"}; to {"ipAddress", "logLevel"};

• Set refactedKeys config default parameters to {"password", "secret", "Authorization", "Cookie"};

Testing

Added and updated tests for filtering mechanism and redactedKeys mechanism.
