bitbake: asyncrpc: Add option to set log level when running as a process

When running an asyncrpc server as a subprocess, it is often desired to
run it with a lower logging level since the normal logging of clients
connecting and disconnecting is not desired.

As such, add an option to set the logging level of the server when
running as a subprocess and set the level to WARNING when starting a
local hashserver or PRserver
