Avoid sed bundled with Darwin for building test images

**What this PR does / why we need it**:
using plain old `sed` we run into problems on macOS. for example when you try `make all-container WHAT=net` under test/images. We should use the same pattern we use in all our scripts to ensure we use gsed or a version of sed from GNU.

At present, `auto_unmount` option is recorded at PV annotation of glusterfs PV.
Due to the preference given in MountOptionFromSpec() for annotation mount options
over sc supplied mount options(Ref PR# https://github.com/kubernetes/kubernetes/pull/66576),
the sc supplied mount options are not honoured in glusterfs plugin
eventhough the driver returns `true` for storage class mountoptions
support at probe.
This patch removes `auto_unmount` option from annotation of the pv spec.

This change ensures that iSCSI block devices are deleted after
unmounting, and implements scanning of individual LUNs rather
than scanning the whole iSCSI bus.
In cases where an iSCSI bus is in use by more than one attachment,
detaching used to leave behind phantom block devices, which could
cause I/O errors, long timeouts, or even corruption in the case
when the underlying LUN number was recycled. This change makes
sure to flush references to the block devices after unmounting.
The original iSCSI code scanned the whole target every time a LUN
was attached. On storage controllers that export multiple LUNs on
the same target IQN, this led to a situation where nodes would
see SCSI disks that they weren't supposed to -- possibly dozens or
hundreds of extra SCSI disks. This caused 3 significant problems:
1) The large number of disks wasted resources on the node and
caused a minor drag on performance.
2) The scanning of all the devices caused a huge number of uevents
from the kernel, causing udev to bog down for multiple minutes in
some cases, triggering timeouts and other transient failures.
3) Because Kubernetes was not tracking all the "extra" LUNs that
got discovered, they would not get cleaned up until the last LUN
on a particular target was detached, causing a logout. This led
to significant complications:
In the time window between when a LUN was unintentially scanned,
and when it was removed due to a logout, if it was deleted on the
backend, a phantom reference remained on the node. In the best
case, the phantom LUN would cause I/O errors and timeouts in the
udev system. In the worst case, the backend could reuse the LUN
number for a new volume, and if that new volume were to be
scheduled to a pod with a phantom reference to the old LUN by the
same number, the initiator could get confused and possibly corrupt
data on that volume.
To avoid these problems, the new implementation only scans for
the specific LUN number it expects to see. It's worth noting that
the default behavior of iscsiadm is to automatically scan the
whole bus on login. That behavior can be disabled by setting
node.session.scan = manual
in iscsid.conf, and for the reasons mentioned above, it is
strongly recommended to set that option. This change still works
regardless of the setting in iscsid.conf, and while automatic
scanning will cause some problems, this change doesn't make the
problems any worse, and can make things better in some cases.

Avoid overflowing int64 in RoundUpSize and return error if overflow int
**What this PR does / why we need it**:
There are many places in plugins (some I may have missed) that we naively convert a resource.Quantity.Value() which is an int64, to an int, which may be only 32 bits long.
Background, optional to read :): Kubernetes canonicalizes resource.Quantities, and from what I have seen testing creating PVCs, decimalSI is the default. If a quantity is in `decimalSI` format and its value in bytes would overflow an int64, e.g. `10E`, nothing happens. If it is in binarySI and its value in bytes would overflow an int64, e.g. `10Ei`, it is set down to 2^63-1 and there's no overflow of the field value. But there may be overflow later in the code which is what this PR is addressing.
* Change `RoundUpSize` implementation to avoid overflowing `int64`
* Add `RoundUp*Int` functions for use when an `int` is expected instead of an `int64`, because `int` may be 32bits and naively doing `int($INT64_VALUE)` can lead to silent overflow. These functions return an error if overflow has occurred.
* Rename `*GB` variables to `*GiB` where appropriate for maximum clarity
* Use `RoundUpToGiB` instead of `RoundUpSize` where possible

Autoset OpenAPI version w/o SecurityDefinitions
There's code to automatically populate OpenAPI info based on existing
generic apiserver config, but it only fires if securitydefinitions are
present. This doesn't make much sense, since this info is both required
and independent of security definitions, and there's no easy, generic
way to generate security definitions for an aggregated API server.
**Release note**:
```release-note
Properly autopopulate OpenAPI version field without needing other OpenAPI fields present in generic API server code.
