Spring dependency should be optional and not provided.

It appears that the only use of Spring is with the XMemcachedClientFactoryBean, so your core functionality does not require Spring be provided for the core functionality of the lib. In this case it's recommended that the dependency have a scope of "optional" instead of "provided".

I would be happy to issue a PR if you agree.

Thanks!

Start by locating the Spring dependency declaration in the project build configuration and confirm how the library uses Spring. Change the dependency scope from "provided" to "optional", then verify that core functionality does not require Spring to be supplied.
