Add user.external_url extended attribute (replaces #2924)

[HereThereBeDragons]

Extension of PR #2924

• Added NULL check for external_downloadmgr
• Extended integration test 615
• Rebased it to match devel

Problems with test 615:

• Extra check for has_correct_external_url works
  BUT following fails:

1 ) line 227

  create_stratum1 $CVMFS_TEST_615_REPLICA_NAME          \
                  $CVMFS_TEST_USER                       \
                  $CVMFS_STRATUM0                        \
                  /etc/cvmfs/keys/${CVMFS_TEST_REPO}.pub || return 110

with Installing GeoIP Database... CVMFS_GEO_LICENSE_KEY not set fail
2 ) rm ${repo_dir}/external/file || return 91 line 244 with
rm: cannot remove '/cvmfs/just.test.repo/external/file': Function not implemented

Commenting both sections out will make the test pass.

@HereThereBeDragons On your first point: we have a key that we use for testing. You can check our Jenkins managed nodes, in /etc/cvmfs/server.local. I can also give it to you privately.

[jblomer]

The second point (rm ...external/file): that should work. Is it just failing on your local system? If so, we should investigate.

@HereThereBeDragons One more change needed: please add test 615 to the quick suite, otherwise it will not run as part of the standard CI tests.

@jblomer added test to quick suite

running the test local, inside cern network the command below does not fail anymore

2 ) rm ${repo_dir}/external/file || return 91 line 244 with

Actually, this may be a problem of overlayfs on XFS with ftype=0 (known overlayfs issue)
