Worker image is hardcoded in cluster.py

[mapsacosta]

We are currently just assuming that the latest coffea-dask image is what the user wants, this is no longer the case as we need to be able to adjust it as needed.

A breaking change upgrading to python3.10 in docker-coffea-dask motivated this use-case.

https://github.com/mapsacosta/htcdaskgateway/blob/main/src/htcdaskgateway/cluster.py#L70 <--- this is where the image is hardcoded

It would be ideal for someone to go:

gateway = HTCGateway()
cluster = gateway.new_cluster(image_name=f"/cvmfs/unpacked.cern.ch/registry.hub.docker.com/coffeateam/coffea-dask-cc7-gateway:<your_version")

@Nanoemc let's use this issue to follow-up on the testing for this feature

A similar problem still exists, where the image prefix is hardcoded in:

htcdaskgateway/src/htcdaskgateway/cluster.py

Line 84 in 8e01209

image_name = f"/cvmfs/unpacked.cern.ch/registry.hub.docker.com/" + self.condor_image

It would be nice to have the option to specify the full path
