Misleading Parameter Names in Slurm Settings Dialog in XFEL GUI

[kmdalton]

@DorisMai and I are supporting some users this weekend. We noticed a handful of parameter names in the "slurm" configuration of the "advanced settings" dialog box that have confusing names (at least we were confused 😂). We suggest the following changes

1. Rename Queue to Partition
2. Rename "Number of processors per node" to "Number of tasks per node"
3. "Phenix setup script" to "Custom setup script". This is mostly a forward-looking suggestion as more diverse tasks make their way into the XFEL GUI.

1. Queue is the overloaded term used for distinguishing between groups of computers, and was named as such when this was principally an lsf system. Queue is still relevant for at least PBS (eg SACLA). It could be displayed as partition when the slurm option is chosen though.
2. Task per node also seems like a slurm specific thing, so the same solution as 1. could be applied
3. Totes agree on this, as well as renaming 'phenix_task' to 'custom_task', or perhaps keeping 'phenix_task' and adding a 'custom_task' option.

1. Yeah totally makes sense to only change it for the SLURM scheduler pane.
2. I agree. I think this is a SLURM construct.
3. Yeah no need to steamroll the phenix task. But some kind of abstract task definition would be good. Doris can probably handle this one as part of her extensions.
