Add support for configuring options in plugins

[jpower432]

Feature Objective

For the v2 implementation, add a new method to the policy plugin interface to pass global configuration options. The goal of the configuration would be to tune the behavior of the plugin, but not on a granular level (like per policy). The goal would be allowing the plugin to apply the configuration after its initialization, but before any transformation method were called.

Caveats/Assumptions

• This may not be applicable to many plugins, thus it should be optional

Completion Criteria

• The plugin must have a way to specify validation options along with default values. Recommend the configuration be specified in the plugin.Manifest
• In the framework, the plugin should be configured after initialization
• The framework must accept per plugin configuration options and reconcile that with the defaults
