Currently, some circumstances may cause waitForDelete to
never succeed after the pod has been marked for deletion.
In particular, Nodes that are unresponsive and have
pods with local-storage will not be able to
successfully drain.
We should allow drain to ignore pods that have a
DeletionTimestamp older than a user-provided age.
This will allow controllers utilizing kubectl/drain
to optionally account for a pod that cannot be
removed due to a misbehaving node.

Currently, if eviction is supported during a drain operation,
eviction is always used.
This commit allows the user to specify disabling eviction.
This is particularly useful when you wish to ignore
PodDisruptionBudgets after a normal drain has failed for
some time.

This commits allows specifying a context.Context
in the Helper type. This context is utilized to
cancel waitForDelete.

The tool golangci-lint gives a bunch of warnings. This PR solves the easier/less controversial ones, so the code is simpler and a little bit more optimal, since it removes some if conditions.

Recently, kubectl drain has been refactored to be consumeable
as a library. Currently, if a pod cannot be evicted due
to PDBs, we will leak a goroutine.
This commit ensures the goroutine always exists.
