Add support for OMERO.web 5.27.0

[sbesson]

Fixes #84

The internal logic of omeroweb.webclient.tree._marshal_image has changed to support the archived status of the images. This change adjusts the mapr logic consuming this internal API accordingly and declares OMERO.web 5.27.0 as the minimal version

The integration failures are likely unrelated to this build and point to the fact that jinja2 is required by the integration tests through the usage of the deprecated omero.util.populate_metadata module but is not installed as a dependency of omero-mapr.

I am not sure of when this regression was introduced but I cannot see an obvious mechanism for declaring a dependency within the test phase of https://github.com/ome/omero-test-infra. Immediate options I can think of are:

• declaring jinja2 as a dependency of omero-mapr
• declaring jinja2 as a dependency of omero-py and address https://github.com/ome/omero-py/blob/749a68acfc7b1851c165ae75f2c118743d8b1e0d/src/omero/util/metadata_utils.py#L33-L38
• refactor the integration tests to not depend on omero.util.metadata_utils
• refactor the integration tests to use omero-metadata which has a transitive jinja2 dependency. It would still be preferable to declare this dependency for the tests exclusively as this is not a runtime requirement

Other suggestions/ideas from omero-test-infra maintainers welcome /cc @joshmoore @jburel @will-moore

Closing as this workaround should be superseded by the work in ome/omero-web#577 and a probably upcoming release of OMERO.web restoring compatiblity.

As discussed in ome/omero-web#577 (comment), this application is tightly coupled to the omeroweb.webclient module which deviates from the recommendation established in ome/omero-documentation#1378. This means this app is particularly prone to any change made to the upstream Webclient. Its logic should probably be audited as this might inform which aspects of the webclient could be reasonably exposed as public API for downstreams apps to consume.

I still get this error when I try to deploy a pilot with this PR included:
