Sheepdog is a distributed block storage. This patch enables Sheepdog cluster
as a backend store for glance.
Test:
You can set up a simulated 3 node cluster on the local machine with
following script:
$ sudo apt-get install liburcu-dev
$ git clone git://github.com/collie/sheepdog.git
$ cd sheepdog
$ ./autogen.sh; ./configure --disable-corosync
$ make; sudo make install
$ for i in 0 1 2; do sheep /tmp/store$i -n -c local -z $i -p 700$i;done
$ collie cluster format
Then change the default store in glance-api.conf as sheepdog
