travis: disable integration

[joshmoore]

gh-5800 is currently failing on the integration step. gh-5787 started
trying to fix this but is not yet green. Disabling for the moment.

From #5800: E ln: failed to create hard link '/OMERO/ManagedRepository/11a98b27-9736-488b-bb49-d2c79f903764_2/2018-07/06/07-51-57.322/import_fake_file_1vWFp8d&series=1&extra_args=[\'--transfer=ln\'].fake' => '/opt/omero/server/omero/tmp/omero_omero-server/919/import_fake_file_1vWFp8d&series=1&extra_args=[\'--transfer=ln\'].fake': Invalid cross-device link

Potential fixes:

• Run df in travis to get a list of mounts (maybe they moved /opt onto a separate partition?)
• Move the fake file to under /OMERO/tmp instead to guarantee it's on the same device as /OMERO

Thanks, @manics. Linked to your comment from omero-test-infra, but for the moment since there are other change too, I'd rather just get this in so PRs go green again.

[sbesson]

Thanks all. Agreed with everything above. Merging this immediately to prevent PRs from blocking ongoing PRs to be excluded because of upstream changes. I understand ways to address this problem are investigate independently. Once done, we can look into re-enabling these integration tests.

Move the fake file to under /OMERO/tmp

looks like a good idea. Coming back to this issue is captured on a card or something?
