Adds integration tests for the following scenarios with
MultiCIDRRangeAllocator enabled:
- ClusterCIDR is released when an associated node is deleted.
- ClusterCIDR delete when a node is associated, validate the finalizer
behavior, make sure that deleted ClusterCIDR is cleaned up after the
associated node is deleted.
- ClusterCIDR marked as terminating due to deletion must not be used for
allocating PodCIDRs to new nodes.
- Tie break behavior when multiple ClusterCIDRs are eligible to
allocate PodCIDRs to a node.

The ClusterIP allocator tries to reserve on part of the ServiceCIDR
to allocate static IPs to the Services.
The heuristic of the allocator to obtain the offset was taking into
account the whole range size, not the IPs available in the range, the
subnet address and the broadcast address for IPv4 are not available.
This caused that for CIDRs with 16 hosts, /28 for IPv4 and /124 for
IPv6, the offset calculated was higher than the max number of available
addresses on the allocator, causing this to panic.

we are saving this information in an env variable `KUBE_INTEGRATION_ETCD_URL`
So just pick it up from there when needed. Currently when someone uses
framework.RunCustomEtcd directly, the global variable is *not* set and the
code that uses `GetEtcdURL` returns empty string.

The GlogSetter method is used by three components to change verbosity at
runtime through HTTP APIs. This used to work only for text output with klog
calls, but not for text output through the klog logger or for JSON output.
Now loggers can also provide a callback for changing their verbosity at
runtime. Implementing that implies that the Create factory method has to be
extended, which is an API break for the Go package, but not an API break for
the configuration file and command line flags, which is what matters for the
"api/v1" component API.
This significantly reduces the surface area of the fieldmanager package
by hiding all the private "managers" objects, as well as the interface
that was made specifically for these. There is no reason to configure
these.
Before, in RunPostFilterPlugins, we didn't distinguish between unschedulable and unresolvable
because we only have one postFilterPlugin by default, now, we have at least two, we should
make sure that once a postFilterPlugin returns unresolvable, we'll return directly
