Skip ImageVolume extension E2Es #108
Description
ImageVolume E2Es require postgis and pgvector extension container images, which in the case of this project should be compatible with the trunk image being built from source.
That means that each extension container images should also be built from source, on top of the most recent trunk image, and hosted in this project.
Also, at every single rebuild of the trunk image we would also have to rebuild all the extension container images, otherwise they wouldn't be compatible anymore with the new trunk since it's built from source.
That's probably out of scope for this project, given that now imageVolume extension testing is also being done as part of https://github.com/cloudnative-pg/postgres-extensions-containers.
So, testing of "trunk" extension container images is deferred to when there's going to be official extensions' PGDG packages for the new incoming PostgreSQL release. That way they can be added and tested directly as part of https://github.com/cloudnative-pg/postgres-extensions-containers.
