Starting grin-miner with missing plugins directory does not generate a user-facing error

[thorsteneb]

Starting grin-miner when the plugins directory is missing will create an error message in grin-miner.log, but grin-miner itself is happy to continue running, be connected to grin, and show "starting miner and awaiting first graph time". Expected behavior: User-facing error that the configured plugin can't be found, or the plugin directory is missing entirely.

Error message in logs for that:

Aug 07 16:15:05.091 ERRO Unable to load cuckoo-miner plugin directory, either from configuration or [exe_path]/plugins.

Aug 07 16:15:05.108 ERRO

Likely related issue, please let me know whether to track separately:

When shutting grin-miner down, with plugin directory missing, it will exit the UI, then just sit there and not terminate. Likely related to the above. Shell at that point looks like this

yorick@Meep:~/grin-miner$ grin-miner
Starting Grin-Miner from config file at: /home/yorick/grin-miner/grin-miner.toml
Starting Grin Miner in UI mode...

and logs show

Aug 07 16:21:06.194 DEBG Client recieved message: Shutdown

Aug 07 16:21:06.195 DEBG Shutting down client controller

A ctrl-c is required to shut down grin-miner
