Updating to ImageN 0.9.3-SNAPSHOT

[jive]

I am coordinating updating to ImageN 0.9.3-SNAPSHOT across several projects.
The key reason for coordination is artifact name change to always have an imagen prefix.

• artifact imagen-core .. unchanged
• artifact affine … becomes artifact imagen-affine

I am starting by disabling downstream build-server jobs, and will enable them again in turn as SNAPSHOT jars are produced.

• Consistently use imagen- prefix for module names eclipse-imagen/imagen#160
• Update imagen.version to 0.9.3-SNAPSHOT geosolutions-it/imageio-ext#493
• Use imagen prefix dependences geosolutions-it/imageio-ext#495
• [GEOT-7951] Use updated ImageN dependencies (with imagen prefix) geotools/geotools#5820
• Update to ImageN 0.9.3 dependencies where artifacts use imagen prefix GeoWebCache/geowebcache#1568
• Update to ImageN 0.9.3-SNAPSHOT mapfish/mapfish-print-v2#112
• [GEOS-12171] Update to ImageN 0.9.3 (with imagen prefix dependencies) geoserver/geoserver#9792

Well that took a long time, thanks @aaime-geosolutions for merging the last PR.

The build server jobs are re-enabled and are back to green.

It seems that this upgrade has broken Windows WMS 1.1.0 builds (the problem at merge was hidden behind the now reverted chore(deps): bump com.ruleoftech:markdown-page-generator-plugin in /src/extension by dependabot[bot] · Pull Request #9787 · geoserver/geoserver · GitHub)

I see the following in the windows build log

This is causing lots of NPE. Since things are fine on other OS, could this perhaps be a file system issue?

I also noticed the message ERROR [wcs.response] - Unable to acquire a reader for this coverage with format: GeoTIFF somewhere in the build log, not sure if that is relevant.
