Fixed a bug where kubectl drain would consider a pod as having been deleted if an error occurs while calling the API.

Currently, there is no way to supply custom pod filters to
exclude pods meeting arbitrary criteria when using drain
as a library.
This commit adds the ability for developers to add custom
filters to the drain operation when utilizing drain
as a library.
This commit exports certain types that were previously
private to allow for better code reuse.
This commit also adds appropriate unit tests.

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.

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.
