Allow for executing executable commands set from the command line.

[snoby]

Allow any value set in the values field of the extra config argument to be executed.

For example to set number of threads for the processor

amountOfThreads": $(nproc --ignore 1)

will execute the nproc command and subtract 1 from the value returned.

When I use HiveOS to install this link:
Install URL: https://github.com/qubic-li/hiveos/releases/download/latest/qubminer-latest.tar.gz
it ends up running version 1.9.6 instead of 3.1. How can I fix this?
