`ClassNotFoundException com.mysema.commons.lang.Pair` when using with OpenFeign Querydsl 7

[svenrienstra]

Using Spring data rest with the latest version of the openfeign querydsl fork (https://github.com/OpenFeign/querydsl) will result in a ClassNotFoundException for com.mysema.commons.lang.Pair in QuerydslAwareRootResourceInformationHandlerMethodArgumentResolver. They removed the dependency on mysema in this PR: OpenFeign/querydsl#573.

Replacing the com.mysema.commons.lang.Pair import with org.springframework.data.util.Pair would resolve this issue. Would you like me to create a PR with this change?

That's fixed and backported now.
