Description

https://github.com/flux-framework/flux-core

The first level support should be to enable STAT to attach to a running job. My current approach is to support STAT through https://github.com/flux-framework/flux-core/issues/3108#issuecomment-668742651.

Using STAT on LLNL's quartz10, I got:

```
(INFO): Unknown resource manager type: it could be misconfiguration in a rm config file.
(ERROR): read_lmonp_msg returned a negative return code
(ERROR): front end's connection to launchmon engine is disconnected?
```

Research direction

Start with the linked flux-core issue and comment describing the proposed STAT integration, then trace LaunchMON's resource-manager handling that produces the unknown resource manager error. There are no project files or tests named in the issue; done means STAT can attach to a running Flux job without the reported resource-manager and connection errors.
