6e953b2ff3 Separate migration of strategy configuration from the constructing and running the plugins (#999)
* Remove log level from Errors

Every error printed via Errors is expected to be important and always
printable.

* Invoke first Deschedule and then Balance extension points (breaking change)

* Separate plugin arg conversion from pluginsMap

* Seperate profile population from plugin execution

* Convert strategy params into profiles outside the main descheduling loop

Strategy params are static and do not change in time.

* Bump the internal DeschedulerPolicy to v1alpha2

Drop conversion from v1alpha1 to internal

* add tests to v1alpha1 to internal conversion

* add tests to strategyParamsToPluginArgs params wiring

* in v1alpha1 evictableNamespaces are still Namespaces

* add test passing in all params

Both LowNode and HighNode utilization strategies evict only as many pods
as there's free resources on other nodes. Thus, the resource fit test
is always true by definition.

ac3362149b Add RemovePodsViolatingNodeTaints taint exclusion
Add taint exclusion to RemovePodsViolatingNodeTaints. This permits node
taints to be ignored by allowing users to specify ignored taint keys or
ignored taint key=value pairs.

This patch adds the policy(evictFailedBarePods) to allow the failed

disable the policy by default. Address #644.

6fd80ba29c README: Clarify podRestartThreshold applying to the sum over containers
calcContainerRestarts sums over containers.  The new language makes
that clear, avoiding potential confusion vs. an altenative that looked
for pods where a single container had passed the configured threshold.
For example, with three containers with 50 restarts and a threshold of
100, the actual "sum over containers" logic makes that pod a candidate
for descheduling, but the "largest single container restart count"
hypothetical would not have made it a candidate.

Also shifts labelSelector into the parameter table, because when it
was added in 29ade13ce7 (README and e2e-testcase add for
labelSelector, 2021-03-02, #510), it landed a few lines too high.
