Add setLogLevel to labRemote Logger and expose it to Python bindings
This MR adds a new static method setLogLevel to logIt and exposes it to the labRemote Python bindings, together with the loglevel_e enum. This allows to set the labRemote logging level from Python, for example:
import labRemote
labRemote.setLogLevel(labRemote.loglevel_e.logERROR)
