Remove create_export from volume create
Currently the LVM driver creates iscsi targets on
volume creation, even though it's only used at
attach time. This isn't necessary and in fact
causes issues if a volume is extended because the
target information isn't currently updated after the
extend. In addition a number of other drivers inclduing
the LIO iscsi driver require the target be created with
initiator info, so the tgt that's created initially
again isn't valid.
This change removes the create_export call from the
volume create process and makes it part of the
managers intialize_connection routine which is
more appropriate.
This change also removes the target on detach since
it's not used any longer and again as the volume may
be modified or extended.
Time unit is missing in the description of vmdk driver option
"vmware_task_poll_interval". Due to this, the vmdk driver config
reference document doesn't have the timeunit in its description
column. This fix adds the missing time unit (seconds) in the
driver option.

Allow spaces in host names in the storwize driver
Storwize/SVC naming rules allow host objects to have spaces in their
names. The SSH injection filter will currently reject such names, and so
we surround the names with quotes. Please note that this doesn't allow
to have an arbitrary character in there except a space (anything else
will be cleaned up by the driver or rejected by the SSH injection filter
up the call chain).

Add support for special char in volume metadata
Using special characters such as "&" in volume metadata caused SAX
parser to split text into multiple child nodes, as stated in the
specs for SAX parsers. In this case extract_text would return
'None' because text was return if there was exactly
one child node. Concatenating the values of child nodes accounts
for SAX parsers splitting contigous characters into

Revert initialize_connection changes
A change was merged that reusulted in interittent
gate failures. It seems that in certain cases the
intitialize is doing an update targets and is
deleting the existing targets and not recreating them.
The idea of this patch was to fix up the iscis targets
for cases where volumes are extended.
A better solution is in progress that will remove the
target creation from the create_volume process altogether.
Currently we seem to have create_export, ensure_export and
now initialize that all are designed to do very similar
things.
A bug has been filed to address this and will attempt
to collapse these functions to be done at attach time.

VolumeManager: initialize even if a volume can't be found
If a previously volume cannot be exported (for example, because
an iSCSI target's backing LV is no longer present), VolumeManager
would previously bail out, leaving the volume service uninitialized.
This left volumes dangling in limbo: their state would be reported
as available (clearly not a reflection of reality), and they could
not be deleted (because the volume service that would be responsible
for deletion was unavailable).
Instead, catch an exception raised by ensure_export() separately,
log it, and set the volume to the error state.
For the tgt backend, this will also remove the volume_path file.
Previously this would cause an ISCSITargetRemoveFailed exception
when the volume would be removed. Instead, simply log a warning
and return, the way other backends (example: RBD) already do.
Also, add an info message that reflects the actual path and
contents of the volume_path file.
Finally, fix up the tgtadm unit test so that it tests for
identical IQNs,

Make sure report_interval is less than service_down_time
Services that inherit service.py/Service class would register
themselves to DB and then update stats periodically (every
report_interval second). The consumer of this kind of information,
like scheduler or 'os-service' API extension, will consider a service
is 'up' (active) if last update from that service is not longer than
'service_down_time' ago.
The problem is if 'report_interval' was configured/provided greater
than 'service_down_time' by mistake, services would then be always
considered in 'down' state, which can result in unsuccesful placement
of volume create request for example. This is what Bug #1255685 is
about.
In previous fix: https://review.openstack.org/#/c/60760/, a
configuration check helper function basic_config_check() was added
*wrongly* to WSGIService class instead of Service class. This patch
moves the configuration check helper function and the check to the
right place to make sure 'report_interval' is less then
'service_down_time'.

Fix up the way we do iqn variable in unit test
A recent bug was reported when a developer was trying to work
with the iscsi target unit tests. There were two problems discovered,
one of which has been addressed by the dependent patch of this commit
(https://review.openstack.org/#/c/68223/) which fixed the inconsistencies
in the string we used for iqn's in our test.
This patch addresses another issue that's somewhat related and was
exposed when the developer tried to use the "self.target_name" variable
instead of hard-coding the iqn's in the tests.
The problem is that the target_name variable uses an invalid format
for the iqn based on cinder-defaults. It neglected to use the
volume_name prefix (in this case: "volume-").
This patch modifies the self.target_name variable to be more accurate
with what we would see in real usage, it also modifies the test to just
use this variable rather than hard coding it and running the risk of
having mismatches again in the future.
