- Use volumes_from instead of volumes so kompose can match up paths properly.
- Mount pgadmin4 without volumes when using kompose for now.
- Annotate the services that should be exposed externally with kompose labels in the source compose files.

…ame when specified.

This is helpful for Kompose.

Relevant pieces of SLURM docs:

```
Node names can have up to three name specifications: NodeName is the name used by all Slurm tools when referring to the node, NodeAddr is the name or IP address Slurm uses to communicate with the node, and NodeHostname is the name returned by the command /bin/hostname -s. Only NodeName is required (the others default to the same name), although supporting all three parameters provides complete control over naming and addressing the nodes. See the slurm.conf man page for details on all configuration parameters.
```

```
ControlAddr
Name that ControlMachine should be referred to in establishing a communications path. This name will be used as an argument to the gethostbyname() function for identification. For example, "elx0000" might be used to designate the Ethernet address for node "lx0000". By default the ControlAddr will be identical in value to ControlMachine.
