Support bulk deletion for commands that exist in both network and compute.

Some delete commands in networkv2 are exist in both network
and compute, They can use NetworkAndComputeDeleteclass to
supprot bulk deletion and error handling and the codes are
similar, so I change them all in this patch. The changed
commands including:
1.floating ip delete
2.security group delete
3.security group rule delete
Also, I update unit tests and docs for these commands in this patch.
