Merging fixes from roxy: removed unused pid_directory attribute and fixed bug where image_cache_stall_timeout in gui is ignored [1/1]

This pull request merges in 2 fixes from roxy:
Fixed bug where image_cache_stall_timeout configured in GUI is ignored
https://github.com/crowbar/barclamp-glance/pull/154

The glance add/edit form allows you to set the value of image_cache_stall_timeout. In glance-cache.conf.erb though, it was referencing an attribute called image_cache_stall_time. This caused image_cache_stall_time to be set to nothing in the resulting glance-cache.conf file.

To test this fix, create a glance proposal setting the value of image_cache_stall_timeout to some value in the GUI, or just note the default value. Deploy glance, then on the glance node as root:

grep image_cache_stall_time /etc/glance/glance-cache.conf

Verify it is set to the value entered in the GUI.

Removed unused attribute from glance default.rb
