Artem Bilan 0f7488f84c GH-369: Fix HeaderEnricher for no proxyBeanMethod (#376)
Spring Boot `@AutoConfiguration` comes now with a `proxyBeanMethods = false`,
so we cannot call bean methods within the same configuration class.

* Rework `HeaderEnricherFunctionConfiguration` for bean methods autowiring
* Create an `ExpressionEvaluatingHeaderValueMessageProcessor` instances directly
in the `headerEnricher` bean definition and propagate an injected `BeanFactory`
* Re-enable disabled tests

Fixes #369

# Header Enricher Function

This module provides a header enricher function that can be reused and composed in other applications.

## Beans for injection

You can import the `HeaderEnricherFunctionConfiguration` in a Spring Boot application and then inject the following bean.

`headerEnricherFunction`

You can use `headerEnricherFunction` as a qualifier when injecting.

Once injected, you can use the `apply` method of the `Function` to invoke it and get the result.
