Add ProgressSpoke

Add a standalone spoke that reports progress of configuration tasks.
This is heavily based on ProgressSpoke from anaconda itself, with few
minor differences:
 - logic for "continue"/"reboot" buttons removed
 - automatic close on finish (as initial-setup normally does)
 - add basic error reporting - anaconda has elaborate exception handling
   machinery but initial setup doesn't; add simple try/except in the key
   place, so user will see the error, not a silent failure
