External configuration data for rules

[BernieWhite]

Currently it is easy to define rules with hard coded conditions. A better approach would be to allow conditions to pull in configuration as required.

Adding a common configuration model for rules will make creating configurable baselines much easier.

Rule configuration must be able to support default values, only non default values should need to be set in configuration.

Consider:

rules:
  configuration:
    rule1_config: value1

Rule 'rule1' {
  $option = Configure @{ 'rule1_config' = 'defaultValue' }
  $option.rule1_config -eq 'value1'
}

For performance reasons it may be better to include configuration as a property of the rule block.

For example:

Rule 'rule1' {
  $Rule.Configuration.rule1_config -eq 'value1'
} -Configure @{ 'rule1_config' = 'defaultValue' }
