    @aljoscha I'm sorry, I cannot follow? Can you elaborate?
    
    The idea is to add support for proper folders next to jars when opening an execution environment.
Since folders cannot be handled the same way as jars during execution (i.e., serialize and
ship them around by the blob manager), the assumption for folder paths is that they are accessible
from all agents in the distributed runtime (JobManager + TaskManagers), e.g., via shared NFS
folders.

> Currently, there is no option to add customs classpath URLs to the FlinkUserCodeClassLoader.
JARs always need to be shipped to the cluster even if they are already present on all nodes.
> It would be great if RemoteEnvironment also accepts valid classpaths URLs and forwards
them to BlobLibraryCacheManager.
