environments, this patch is used to remove dependency to the
old aggregate-based-pools and add support to xenapi pool.
Also include unit test changes.
Updated configuring migrations document:

XenServer Pools with shared storage used to use aggregates in Nova,
however this support was not adequately tested and became broken in
a previous release.
Now live migration with shared storage is possible using native
XAPI pools - independently of Nova's aggregates.
The XenAPI/Nova integration expects one nova-compute per XenServer
host, so a nova-compute must be run for each slave XenServer host
in the pool as well as for the master.
