[PATCH v2 1/2] bitbake: xmplrpc: split connect method

[Ed Bartosh <ed.bartosh@linux.intel.com>]

Current code in connect method sets up event queue, which requires
registering UI handler. This functionality may not be needed for
some operations, e.g. for server termination.

Moved functionality of setting up event queue in from 'connect'
method to 'setupEventQueue' in BitBakeXMLRPCServerConnection class.
