Adding logrotate as eos tends to generate plenty of logs and eos-server does not depend on logrotate. This helps a lot for long stress tests.

Upgraded to EOS 4.4.25-20190220154847git43a58c0 in order to get the new logs of the WFE::Job::SendProtoWFRequest() method

Upgraded to eos version4.4.25-20190208164812gite195333 in order to test simplifications of eos::mgm::TapeAwareGc

We are supposed to stick in the loop for 30 seconds until nothing more comes out, but
this only worked for retrieves (archive reports failed to loop).

CatalogueTest now asserts new archive file identifiers are unique as opposed to strictly incrementing sequentially by 1

Woah!  Got carried away with const.  This commit Removes the const
qualifier from the ArchiveFileItor::next() method because next()
modifies the iterator.

To loop through an ArchiveFileItor:

  auto itor = catalogue.getArchiveFilesForRepackItor(vid, startFSeq);
  while(itor.hasMore()) {
    const auto archiveFile = itor.next();
    // Do something with archiveFile
  }

It was using vid as container identifier where it should have used
tapepool.

Previously these were references, but sometimes we want only an archive
queue itor or only a retrieve queue itor. Now we can set the unused
itors to nullptr.
