LVM migrate: Use keywords for the brick instance
In the `migrate_volume` method a new instance is created when the
dest_vg is not equal to the source vg. This new brick instance is
created using positional arguments instead of keywords. However, some of
those arguments are passed in the wrong positions.
This patch uses keywords for the misplaced arguments.
The patch also changes `test_lvm_migrate_volume_proceed` in order to
fully test the happy path and catch things like this.

LVM: Create thin pools of adequate size
Thin pools in LVM are quite different from volume groups or logical
volumes and their differences must be taken into account when providing
thin LVM support in Cinder.
When you create a thin pool, LVM actually creates 4 block devices. You
can see this after thin pool creation with the following command:
In the above command, a thin pool named 'volumes-1-pool' was created in
the 'volumes-1' volume group. Despite this, the 'lvs' command will only
show one logical volume for the thin pool, which can be misleading if
you aren't aware of how thin pools are implemented.
When you create a thin pool, you specify on the command line a size for
the pool. LVM will interpret this size as the amount of space requested
to store data blocks only. In order to allow volume sharing and
snapshots, some amount of metadata must be reserved in addition to the
data request. This amount is calculated by LVM internally and varies
depending on volume size and chunksize. This is why one cannot simply
allocate 100% of a volume group to a thin pool - there must be some
remaining space for metadata or you will not be able to create volumes
and snapshots that are pool-backed.
This patch allocates 95% of a volume group's free space to the thin
pool. By doing this, we allow LVM to successfully allocate a region for
metadata. Additionally, any free space remaining will by dynamically
used by either data or metadata if capacity should become scarce.
The 95/5 split seems like a sane default. This split can easily (and
probably should) be made user-configurable in the future if the user
expects an abnormal amount of volume sharing.
Catch ImageBusy exception when deleting rbd volume
If we try to delete an rbd volume that has 'watchers' on it
i.e. client connections that have not yet been closed
possibly because a client crashed, the remove() will throw an
ImageBusy exception. We now catch this exception and raise
VolumeIsBusy with a useful message.
If the volume delete fails in this way it will now stay as
'available' instead of going to 'error_deleting' so that the
delete can be retried (since it is expected to work on a
retry after waiting for the connection to timeout).

Parse out '@' in volume['host'] to do discovery
The backup method of getting iscsi info is to use
iscsiadm discovery, however currently that method
just uses volume['host'] which in the case of

This will cause the discovery to fail of course, so
this change just parses out the '@' symbol if it's present

This also beefs up the error logging and exception catching
a bit.
Parsing out the '@' symbol all the time should be safe as
the accepted valid chars for hostnames are digits, a-z and
