* Added a extractor to extract raw logs from json format and then pipe
it into benchmark parser.
* Also added -alsologtostderr=false -logtostderr=false to reduce noisy logs.
AWS eventual consistency can go back in time. It can return that a volume
is detached and then that it is attached.
When this happens during attachment of the same volume to the same node,
but with a different device name, retry DescribeVolumes a few times before
reporting an error. 10 retries should be enough to get a consistent result.
kubeadm's current implementation of component config support is "kind" centric.
This has its downsides. Namely:
- Kind names and numbers can change between config versions.
Newer kinds can be ignored. Therefore, detection of a version change is
considerably harder.
- A component config can have only one kind that is managed by kubeadm.
Thus a more appropriate way to identify component configs is required.
Probably the best solution identified so far is a config group.
A group name is unlikely to change between versions, while the kind names and
structure can.
Tracking component configs by group name allows us to:
- Spot more easily config version changes and manage alternate versions.
- Support more than one kind in a config group/version.
- Abstract component configs by hiding their exact structure.
Hence, this change rips off the old kind based support for component configs
and replaces it with a group name based one. This also has the following
extra benefits:
- More tests were added.
- kubeadm now errors out if an unsupported version of a known component group
is used.

Attempting to add ResourceVersion precondition to
eviction requests results in a conflict failure. This
is due to the fact that we apply a deletion timestamp
which mutates the underlying resource. The resource
version is then checked again later in the code.
This commit removes the ResourceVersion precondition
after the object has a deletion timestamp applied.

"etcd -version" command output an additional line on ARM platform:
"running etcd on unsupported architecture "arm64" since
ETCD_UNSUPPORTED_ARCH is set"
Currently etcd version filtering code can not get correct version
number.
