Currently, client-go requires that an IPv6 address string for hostname has
square brackets surrounding, so that it can be used with address:port in
an API request.
This change, removes that requirement, and has getListener() add the
square brackets for IPv6 addresses for hosts. If IPv4 or hostname, the name
will not be modified.
Decided to change here, rather than everywhere client-go is used (thinking
that there may be places where we DON'T want the square brackets applied).
This issue was found in kubelet, which, at startup, creates a listener for
services and nodes. If an IPv6 address is used, the URI was malformed.
This behavior regressed in an earlier release. Clearing the self link
ensures that a new version is always written and reduces the size of the
stored object by a small amount. Add tests to verify that Create and
Update result in no SelfLink stored in etcd.

remove svg mime type extension
Signed-off-by: sakeven <jc5930@sina.cn>
**What this PR does / why we need it**:
I found that [kubernetes requires go version 1.6 or greater](https://github.com/kubernetes/kubernetes/blob/master/hack/lib/golang.sh#L335).
While the [commit](21e47d831b) which adds "image/svg+xml" type for extension ".svg", has been merged to go from version 1.5 to 1.9beta.
So it's safe to remove code ```mime.AddExtensionType(".svg", "image/svg+xml")```.

IPv6 support for getting IP from default route
This is another part of the effort to update ChoseHostInterface() to support
IPv6. In particular, this focuses on the call path, starting from
chooseHostInterfaceFromRoute(), which attempts to find the node IP by
using default route information.
In the original code, routes are collected, and examined to find default
routes. For a default route, the IPs for the associated interface are
checked to see if there is one that is a V4 address, and is not a
loopback, link local, or multicast address. If found, that IP will be
used for the node IP.
With this PR, there are some slight changes to prepare for allowing IPs
from IPv6 default routes. The routes (IPv4 at this time - a subsequent
PR will handle IPv6) are collected as before. If the route is a default
route AND it's GW address is a global unicast address, then the IPs
for the associated interface are checked. This time though, we just pick
the IP that is on the same subnet as the gateway IP.
This ensures it is not a link local, loopback, or multicast address. It
saves time, by nt checking IPs for interfaces that don't have a "global"
default route. It also will ensure the right IP is used, when using both
IPv4 and IPv6 addresses.
For example, if we have eth0 with global IPv4 and IPv6 addresses, and
an IPv6 default route, we want to select the IPv6 address, as it is
associated with the default route.
Another case is that same interface, along with eth1 containing an IPv4
address with a default route. We want to select eth1's IPv4 address,
and not the IPv4 on eth0.
This change adds more UT coverage to several methods, and removes UTs
that are redundantly testing at a higher level. Coverage is slightly
improved.

fix missing resource method in register.go
In jsonpath, when filtering a list, if allowMissingKeys is true, skip
over any items that are missing an intermediate key in the filter,
instead of returning a confusing error.
For example, if the filter is
{.items[?(@.metadata.annotations.foo=="bar")].metadata.name}
we should return all items where metadata.annotations.foo == bar, but if
an item in the list does not have metadata, metadata.annotations, or
metadata.annotations.foo, skip it instead of erroring.

audit: fix deepcopy registration
Remove manual registration into scheme by fixing the deepcopy tag of the api group.
This is part 2 of the effort to update ChoseHostInterface() to support IPv6
addresses (as part of issue 44848). This changeset includes:
- Supports finding IPv6 host addresses from default routes (but currently only
provided with IPv4 default routes).
- getRoutes() filters for default routes.
- getFinalIP() checks that IP is in requested family. Uses IsGlobalUnicast(),
instead of explicit tests for loopback, multicast, and link-local IPs.
- getIPFromInterace() checks for family requested.
- chooseHostInterfaceFromRoute()
* Quickly exits, if no default routes.
* Since only getting default routes, no check here.
* Searches all default routes for IPv4 addresses, and then searches all
default routes for IPv6 addresses (for backwards compatibility).
- More coverage in UTs (87.8% vs 62.6%).
- Better testing of error conditions/results.
- Tests for IPv6 IPs, throughout functions.
- Reduced duplicate testing for items tested at lower levels.
Commit has been rebased on top of PR46044.
