Rename RepositoryInvocationMulticaster for consistency [DATACMNS-1805]

[spring-projects-issues]

John Blum opened DATACMNS-1805 and commented

The RepositoryInvocationMulticaster should be renamed to RepositoryMethodInvocationMulticaster to match the names of the (especially) RepositoryMethodInvocationListener along with the RepositoryMethodInvocation and RepositoryMethodInvocationResult classes for consistency's sake.

This should be relatively easy to do since the interface was added in 2.4.0 and is package-private
