Bug#1031123: RFS: libcommons-collections4-java/4.4-1 [Team] -- Apache Commons Collections - Extended Collections API for Java

[min sun <sunmin89@outlook.com>]

Hi, Hilmar Preuße, and tony:

Thanks for you guide!

I will keep the distribution tag "UNRELEASED" as it is for the sponsor.

The debian/watch was modified to direct to apache archive site ,because:

1.Tag names from github are not well defined[1].
2.Some github release even introduces nonexisted files[2].

I think the apache site will do a little more strict check before archiving
