Add inclusion/exclusion filtering configuration for ExtraDirectories in Maven and Gradle

[chanseokoh]

Adds new "includes" and "excludes" config parameters in Maven and Gradle.

Previously, RawConfiguration returned a map (for <from> --> <into>), but since now it requires two more fields, we should return a structure.

Toward #2564 (and #3164).
