Convert OMERO strings to unicode

[manics]

Fixes https://trello.com/c/lLxHorjS/5609-prom-exporter-unicodedecodeerror

OMERO rstrings may contain unicode, but they are not automatically converted to Python unicode. This solution involved some trial-and-error.

Testing: omero-prometheus-tools.py -s pub-omero.openmicroscopy.org -u PRIVILEGED-USER -w PASSWORD -v -c etc/prometheus-omero-counts.yml against a server that has Unicode group names e.g. pub-omero and go to http://localhost:9449/

Added a test (uses modified omero-test-infra)

Though looks like travis isn't enabled on this repo.

In general, 👍 for dealing with unicode and 💯 for adding the tests.

Continuing the conversation from ome/omero-test-infra#22, I'm pretty sure this could be accomplished with test-data and lib-test files, but we can discuss that there.

Most relevant question here is if a unicode-aware unwrap method (or something else) would have helped you here.

Also, is "Login as микроскопом-пони fails with a unicode error so create" written up somewhere?

[manics]

Thanks, I've got it working with test-data and lib-test based on ome/minimal-omero-client#27
There's a bug though: ome/omero-test-infra#24

Closing and re-opening to trigger travis.

Think this should probably be in the upstream lib-test and/or docker script as well.

Nicely done. Shall his become 0.1.1?

[manics]

👍 for 0.1.1.
