Method setup_logging in glance/common/config.py wasn't used anywhere.

Remove "image_cache_invalid_entry_grace_period" option

 "image_cache_invalid_entry_grace_period" option is unused
in *.py, but the option is used in glance-cache.conf.

 I removed "image_cache_invalid_entry_grace_period" option
from glance-cache.conf.
