Fix cache auto configuration

[msdousti]

Using Riptide without caching enabled must not require httpclient5-cache.

Description

• Fixed RiptideProperties such that it does not require org.apache.hc.client5.http.impl.cache.CacheConfig.
• Fixed org.springframework.boot.autoconfigure.AutoConfiguration.imports to have separate configs for main and test (otherwise, production code would require MockRestServiceServer to be in class path)
• Updated README.md to use httpclient5-cache instead of httpclient-cache.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Checklist:

• My change requires a change to the documentation.
• I have updated the documentation accordingly.
• I have added tests to cover my changes.

Interesting that you need to add this annotation as @ConfigurationProperties should normally make this available to Spring.

Intellij showed an error saying not registered via @enableconfigurationproperties or marked as spring component.

The project compiled anyway, but I followed the advice here:

This is expected as @ConfigurationProperties does not make a class a Spring Component. Mark the class with @component and it should work. Note that a class can only be injected if it is a Component.

Thanks for the insights. Yes, I remember that you have to add this annotation to your main class for example, to get this working. I guess, given that this is a library, it makes sense to follow that approach.
