Use Customizer instead of Bootstrap Config

[SentryMan]

It occurs to me that using Bootstrap (which runs immediately before every other form of config) runs the risk of having its configurations overwritten by the inject plugin causing some perhaps unexpected results. I'm thinking to make the primary way of configuring the validator (outside of directly calling the builder functions) be via the customizer interface.

• rename ValidatorComponent to ValidatorCustomizer (I just think it sounds cooler and is more descriptive)
• remove the bootstrap interface
• adds an annotation to automatically add ValidatorCustomizer entries to the services file
